Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fragrances. It plays a role in the preparation of certain flavoring agents due to its phenolic and carboxylic functional groups, which allow for esterification and derivatization. Commonly found in the synthesis of vanillin-related compounds, it contributes to the development of aroma chemicals and UV-absorbing molecules. Also investigated for use in antioxidant formulations owing to its phenolic structure.
