Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the production of anticoagulants and coumarin derivatives. It serves as a building block in organic synthesis due to the presence of both aldehyde and phenolic functional groups, enabling condensation reactions and Schiff base formation. Also applied in the development of fragrances and flavoring agents owing to its aromatic characteristics. Its derivatives are explored in coordination chemistry as ligands for metal complexes with potential biological activity.
