Used as a key intermediate in the synthesis of various pharmaceuticals and natural products, particularly in the development of alkaloids and flavonoids. Its functional groups—aldehyde, hydroxyl, and bromo—allow for selective reactions, making it valuable in building complex organic molecules. Commonly employed in cross-coupling reactions due to the bromine atom, enabling carbon-carbon bond formation. The aldehyde group facilitates condensation reactions, useful in creating Schiff bases or extending aromatic systems. Also applied in the preparation of bioactive compounds with antimicrobial or anti-inflammatory properties.
