Acetylating agent for capping unreacted amino groups in peptide synthesis. | [Definition]
ChEBI: N-acetylimidazole is a N-acylimidazole. | [General Description]
Rate of solvolysis of 1-acetylimidazole in acid solutions was evaluated. Reaction of 1-acetylimidazole with orthophosphate and adenosine-5′-phosphate has been reported. | [Purification Methods]
It is recrystallised from isopropenyl acetate and dried in a vacuum over P2O5. [Riordan & Valee Methods Enzymol 25 500 1972, Beilstein 23/4 V 218.] |
