Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and functionalized aromatic compounds. Its bromoethyl group allows for further alkylation or coupling reactions, making it valuable in the development of drug candidates targeting central nervous system disorders and anti-inflammatory agents. Commonly employed in the synthesis of esters and amides through activation of the carboxylic acid group. Also utilized in polymer chemistry to introduce aromatic and reactive functionalities into macromolecular structures.
