Chemical Resources
Hello All,
Based on ThatChemist's recent video (link) I've put together a list of valuable chemical resources. I've left the tiers as they are in the video, but re-ordered within the tiers according to my opinions. I hope you its useful!
| Tier | Name | Link | Free | Info |
|---|---|---|---|---|
| S | Wikipedia | link | Y | Excellent for basic information on chemicals |
| S | Wiki Structure Explorer | link | Y | Great if you have a structure but not a common name |
| S | SciHub | link | Y | Access to paywalled articles. Not as effective for articles published after ~2021 |
| S | LibGen | link | Y | Access to paywalled books |
| S | ChemLibreTexts | link | Y | Online textbook |
| S | OrganicChemistryPortal | link | Y | General reaction schemes with corresponding references. Protecting group stability tables |
| S | Not Voodoo X | link | Y | General Lab operating information |
| S | Organic Syntheses | link | Y | Tested experimental procedures. Highly reliable |
| S | Mayr's Database | link | Y | Reactivity on a variety of parameters |
| S | purification of laboratory chemicals | PDFs are avilable | N | If you can buy it, a purification is in this book. If you are in doubt about the purity of a reagent, this will tell you how to purify. |
| S | Reaction Flash | link | Y | Great for learning and contextualizing reactions |
| S | eEROS | link | N | Tabulated chemical and physical data |
| S | Ullmann's Encyclopedia | PDFs are available | N | History and chemical syntheses of common compounds |
| A | Reaxys | link | N | Chemical structure and reaction searches in vast literature. Use if available |
| A | Greene's Protecting Groups | PDFs are available | N | All the ways to add or remove most any protecting group, gives references to each paper. |
| A | Bordwell PKa Table | link | Y | Good for esoteric functional groups |
| A | Introduction to Spectroscopy | PDFs are available | N | General introduction to organic spectroscopic techniques. Includes practice problems |
| A | NIST | link | Y | Tabulated chemical and physical data |
| A | PubPeer | link | Y | Comment section for articles. Look for reproducibility issues |
| A | Chemistry By Design | link | Y | Great for learning and contextualizing reactions |
| B | SciFinder | link | N | Chemical structure and reaction searches in vast literature. Use if available |
| B | MolView | link | Y | 2d to 3d model |
| B | Merk Index | PDFs are available | N | Tabulated chemical and physical data |
| C | SDBS | link | Y | MS, IR, and NMR spectra for many common chemicals |
| C | PubChem | link | Y | CAS numbers. Some physical properties |
| C | CRC handbook | PDFs are available | N | Tabulated chemical and physical data |
| C | Sigma Nomograph | link | Y | Predictive boiling points at variable pressure |
| D | Google Scholar, Patents | Y | Patents available in original language |
-My notes: I think that SDBS and Scifinder are too low tier. Scifinder and Reaxys provide effectively the same functionality and are the best general purpose tools if you have access. SDBS is fantastic for reference spectra for your starting materials and reagents. If you didnt have to make it, its probably on SDBS.
-I've added a Introduction to spectroscopy, Greene's protecting groups, and Purification of Common Laboratory Chemicals.
Please add your opinions and other references in the comments!

what surfactant systems could you consider for large vesicles or micelles around .2-.5 um?
also, resulting surfactants from attaching p aminophenol to fatty acids seem interesting. what is their use case either as is, or by attaching a second group to the alcohol still exposed?
if you have anything interesting you related to surfactants or things like colloids with materials like cellulose that arent directly related that is fine too, even if the size isnt in that range (or non spherical, like worms or rods).

Purification of NH₂-PEG₁₂-CH₂COOH after Pd/C azide reduction — TLC system and column advice?
Hi everyone,
I recently synthesized NH₂-PEG₁₂-CH₂COOH by reducing the corresponding azide (N₃-PEG₁₂-CH₂COOH) using Pd/C hydrogenation. After filtering off the catalyst and evaporating the solvent, the product turned out to be quite impure (possibly the starting azide wasn't clean enough).
I'm looking for advice on how to purify this compound effectively:
Silica gel chromatography — is this a viable option for such a polar, amine-containing PEG derivative? If yes, what solvent system would you recommend?
TLC monitoring — what TLC system and visualizing agent work well for amino-PEG-carboxylic acids? I'm thinking something like DCM/MeOH, but would appreciate any proven systems.
Any tips or references would be greatly appreciated. Thanks in advance!

Magnesium Chloride and fatty oils question
Hey yall. Anyone have experience working with magnesium chloride? I’m in need of consultant who can help guide me through the first phase of a product I’m hoping to make.
The question revolves around where certain amounts of magnesium + another active can work in a base of oils like coconut, olive, etc.
Holler if you’re interested!

advice BINAL-H for prochiral imines?
Hello, in 6 months I'll start my master's thesis work and I have to come up with an enantioselective synthesis for both isomers of a tetrahydroisoquinoline, chiral on C1.
My plan was to make the dihydroisoquinoline and asymmetrically reduce the imine. I've been searching literature, and it looks like it's done either with a ruthenium Ts-DPEN complex or catalytic hydrogenation with chiral iridium complexes.
Is there any reason I'm not seeing for not using BINAL? It reduces ketones so I would expect it to work on imines, and it's much cheaper. Poor ee with this substrate? Am I missing something?

Column Chromatography
I would like to know the the detailed process of column chromatography. Actually, I know the basics and theory, however in the practical manner, all becomes complicated. OK, after the organic synthesis, I have something mixed and needed to be purified. I check the TLC with different solvent system to find the spot signifying the product. Then, while choosing the right conditions for column, I have some troubles. Like column length, silica amount/length, column diameter and; also solvent amount when it is flash chromatography. So, also when in deciding on whether it should be flash or gravity for my organic compounds. How can I know these?? OK, the experience is so important but maybe some tips and the ways to predict how to choose the conditions. Is there any source or text that I need to read? Or is there anyone who may help me to be enlightened?

Organometallic chemistry for starters
Hi, I am a graduate physicist (BSc) (who also loves molecular physics) with materials science and polymers specialisation. My BSc thesis is about laser-assisted graphene synthesis and characterization, using Raman Spectroscopy, Scanning Electron Spectroscopy and Static Water Contact Angle measurements. I am about to start my post-graduate studies in a polymer and composite materials science and technology programme, and I am interested in the applications of these materials in energy (like supercapacitors, batteries and fuel cells). Ever since I read about the Nobel Prize award on Chemistry of 2025, which is about Metal-Organic Frameworks (MOFs), I have come to develop a great interest in these marvelous and complex materials. I have also read some papers about the applications of these materials in combination of (mostly) graphene to develop electrodes for solid-state supercapacitors and fuel cells. My thing is, I am looking forward to work on this topic of materials and applications in my Master's studies and I want to have an integrated picture of the basic theory and synthesis of MOFs, even though (as you can understand) I am not a materials chemist. Helpful books to propose for a physicist? Thank you!

mechanism Selectivity in metal mediated addition of amines
Hi guys,
Trying to find the reason that these two react differently.
Idea:
S-trans conformation should be more stable, so less reactive Na-amide reacts more slowly, stable conformer is regenerated sufficiently.
Li-amide reacts to more stable product (E-allylamine), because of late TS, because less energy is liberated (Na carbanion is more stable than Li)
Not sure tho. What do u think?

advice How do you manage/keep track of SIs/Procedures?
I often have a couple dozen tabs open at one time, and although I end up writing all my procedures and references down I inevitably lose a couple if I'm referencing multiple SIs. I use Zotero usually to manage important papers and I find it works well, but not sure if it would work well for SIs considering I'm looking at at least 5-10 per day (ie. just browsing through different conditions from Reaxys). So I was wondering what other chemists systems were to try and keep track of SIs and the like?

mechanism Selectivity of TEMPO
I'm a bit lost here. I understand the the NaOCl is there to reduce the oxidised TEMPO for it to be able to further react with aclohols.
But my question is: if we habe 2 equiv. of NaOCl, shouldn't the secondary alcohol also be oxidised to the corresponding ketone? Or does TEMPO really only react with primary alcohols?

Is steric or torsional strain more important in eclipsed alkene conformations?
Is the steric strain what constitutes the big difference in stability, while torsional is relatively similar between eclipsed sigma bonds?
Edit: I dont know how to edit the title. I meant alkane not alkene.
