OK so /chem/ i purchased some drugs online but instead they sent me 98% para-hydroxy-cinnamic acid. what id like to know is can i use this despite only being 98% could i use this in the same way as people use acetic anhydride to add acetyl groups to open hydroxy positions specifically in opis at the 3,6,or 14 hydroxy positions? if not is it useful for really anything?

pic related the 25 grams of para-hydroxy-cinnamic acid

Basic 1st year equilibrium reaction laws apply.

You have to make it into an anhydrous with SOCl. This is going to be like acetylation with Acetic Acid. It can't work because it'll generate AcOH before it makes Ac-Morph. that's why you have to make Acetic Anhydride first before doing any acetylation.

wouldnt the carboxyl chloride then attack the phenolic functionality on the HO-cinnamic acid?
i reckon extremely low concentrations of the acylation agent compared to the substrate eg morphinnnnee would reduce the ammount of polymerizedd bullshit.

excuse high and drunk facilitated retardation because i didn't read "para hydroxy" for some weird reason. just protect it using a benzoyl group or some sort of ether.
