Anwendungen

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.
