Used as an acetylating agent in organic synthesis, particularly in the preparation of esters and amides. It serves as a reagent for introducing the acetoxyethyl group in pharmaceutical intermediates. Commonly employed in the synthesis of penicillin and cephalosporin antibiotics due to its ability to modify beta-lactam structures. Also utilized in the production of specialty monomers for polymer chemistry, where it acts as a protecting group or linker in controlled esterification reactions. Its bromo functionality allows for further nucleophilic substitution, enabling sequential synthetic transformations.
