Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its functional groups—aldehyde, hydroxyl, and bromo—allow for diverse chemical modifications, including nucleophilic substitutions, cross-coupling reactions, and condensations, making it valuable in constructing complex molecules. Commonly employed in the development of bioactive compounds, including potential drug candidates with antimicrobial or anti-inflammatory properties, as well as precursors for flavonoids and antioxidants. Also utilized in the synthesis of dyes and fluorescent probes due to its aromatic structure and reactivity.
