Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and functionalized aromatic compounds. Its reactive bromoacetyl group allows for nucleophilic substitution reactions, making it valuable in the development of bioactive molecules and specialty chemicals. Commonly employed in the synthesis of dyes, polymers, and ligands for metal complexes. Also utilized in modifying peptides or proteins through covalent attachment due to the affinity of the bromomethyl ketone moiety for nucleophilic amino acid residues.
