Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its functional groups—bromine, aldehyde, and hydroxyl—allow for selective reactions such as cross-coupling, oxidation, or substitution, making it valuable in constructing complex molecules. Commonly employed in the development of bioactive compounds, including antimicrobial and anti-inflammatory agents. Also utilized in the synthesis of natural product analogs and heterocyclic compounds for medicinal chemistry research.
