Used as a key intermediate in the synthesis of brominated flame retardants, enhancing fire resistance in polymers and resins. Employed in organic synthesis for the preparation of complex aromatic compounds due to its reactive bromine and functional groups. Acts as a derivatizing agent in analytical chemistry, particularly in mass spectrometry, to improve detection of carboxylic acid-containing compounds. Also explored in the development of antimicrobial agents owing to the combined effect of bromine and phenolic structure.
