Used as a selective acetylating reagent in organic synthesis, enabling efficient and controlled acetylation of alcohols and amines under mild conditions. Its selectivity allows for acetylation in the presence of other reactive functional groups without extensive protection-deprotection steps. Commonly applied in pharmaceutical and fine chemical manufacturing where precise functional group modification is required. Offers improved yield and purity in acetylation reactions compared to traditional reagents, with easier handling and reduced side reactions. Suitable for use in automated synthesis and scalable processes due to its stability and predictable reactivity.
