Applicazioni

Acetyl Bromide is used as an acetylating agent in the synthesis of fine chemicals, agrochemicals and pharmaceuticals. It is also used as an intermediate for dyes. Further, it reacts with alcohols and amines to produce acetate esters and acetamides. In addition to this, it is involved in the synthetic process of the anti-HIV agent.

Note

Incompatible with strong oxidizing agents, strong bases and alcohols
