What is URAMIL?
Purification Methods
It crystallises from water. It has also been purified by dissolving it in aqueous ammonia and precipitating it by dropwise addition of formic acid. The solid is collected and dried in a vacuum at 100o. [Hartman & Sheppard Org Synth Coll Vol II 617 1943, Beilstein 25 H 492, 25 I 704, 25 III/IV 4228.]
