Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Serves as a building block in the preparation of bioactive compounds due to the presence of multiple functional groups (aldehyde and phenolic hydroxyls). Its structure supports condensation reactions, making it useful in the development of Schiff bases and other derivatives with potential antimicrobial or antioxidant properties. Also employed in research for synthesizing natural product analogs and in the study of reaction mechanisms involving polyhydroxy aromatic aldehydes.
