Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of heterocyclic compounds. It serves in the development of dyes and fluorescent probes due to its aldehyde and phenolic functional groups, which allow for easy modification. Also employed in the production of UV stabilizers and antioxidants for polymers, leveraging its ability to scavenge free radicals. Its bromine moiety enables coupling reactions in organic synthesis, making it valuable in building complex molecules for research and industrial applications.
