This has been my experience as well, repeated recrystallisations of the lysergic acid from hydrolysis resulting in a powder which becomes lighter brown each time but still not as light/pure as you would expect. Do you recommend column chromatography of the LA or just column chromatography of the...

Hello, What solvent would you use for the purpose of recrystalising the D-Lysergic Acid Hydrate? Would ethyl acetate be suitable? I also have a similar question for the recrystallisation of the lysergic acid diethylamide tartrate if there are any other solvents which the salt would have...

Thank you very much for the help I realise now that I definitely should have been referring to acidic hydrolysis so thanks for pointing out that alkaline hydrolysis would racemize the product. Is it possible for D-LAME to hydrolyze to the carboxylic acid form without the presence of the...

Hi all, If someone were to wish to convert D-LAME (D-lysergic acid methyl ester) into the carboxylic acid form (lysergic acid), would it be standard to do this via hydrolysis of the ester with something like NaOH/KOH then neutralize it with HCL? What temperature could this reaction be done...
