Used as an intermediate in the synthesis of biologically active compounds in pharmaceutical research, particularly in the development of targeted drugs such as kinase inhibitors for cancer or anti-inflammatory agents. Its bromoacetyl group enables further functionalization through nucleophilic substitution, making it valuable in medicinal chemistry for constructing molecules that interact with enzymes or cellular receptors. Commonly employed in the preparation of covalent inhibitors that bind irreversibly to specific enzyme targets. Additionally, it serves as a reagent for labeling molecules in biomolecular studies.
