Definitely more than 20L. Whoops. I’m kind of messy.

I left my spatula in a beaker with our crude product overnight, leading to a very pretty spatula with crystallised product on it the next morning

Creatine is for fancy words a “nitrogenous organic acid.” Its found in meat and fish.

It is also made by your liver, kidneys, and pancreas synthesized from 3 amino acids: Glycine, methoinine, and argenine by two enzymes, arginine:glycine amidino-transferase (aka AGAT) and Guanidinoacetate

Today I’m taking the lactone synthesized last week and using 1M Boron Tribromide in DCM to open the ring halogenate the primary carbon. This reaction is sensitive to air and must be run under nitrogen. When in contact with the air it forms HBr gas.

Free vintage heterocyclic chemistry books. I’m embarrassed to say I was rather excited about this.

The Haber process is the reaction by which ammonia is produced using nitrogen gas and hydrogen gas with the equation;

N2 (g) + 3H2 (g) ↔ 2NH3 (g)

The reaction is reversible as it is in equilibrium. Equilibrium is a condition in which the forward and reverse reactions are occurring at equal…

Flash column chromatography/filtration through silica. This method removes highly polar decomposition/side products in no time and gives a high purity product (that orange thing).
If there are compounds that have a high Rf (retention factor) difference on a TLC (thin layer chromatography), than it means that while compound A with high Rf could be easily separated with a short column with this method from compound B or C what has a low ~0-0,2 Rf.
