1-Acetylimidazole Chemical Properties,Usage,Production

Chemical Properties

white to beige or light tan adhering crystals or

Uses

Acetylating agent for capping unreacted amino groups in peptide synthesis.

Uses

It is a mild acylating agent and its reactivity can be enhanced by quaternization with, e.g. benzyl bromide. 1-Acetylimidazole was used as acetylation reagent for amino groups. It was also employed for acetylation of histones. It is relatively specific reagent for tyrosyl residue acetylatioa dn a reagent used in the synthesis of annulated imidazole derivatives.

Uses

Relatively specific reagent for tyrosyl residue acetylation. Reagent used in the synthesis of annulated imidazole derivatives.

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.]
