Used as an intermediate in organic synthesis, particularly in the preparation of flavonoids and other polyphenolic compounds with antioxidant properties. It serves as a building block in pharmaceuticals, including drugs targeting inflammation and oxidative stress-related diseases. Also employed in the development of dyes and functional materials due to its reactive aldehyde and phenolic groups. Its structural similarity to natural plant metabolites makes it valuable in the synthesis of bioactive molecules and nutraceuticals.
