Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of anticoagulant drugs and vitamin K antagonists. It serves as a building block in organic synthesis due to the presence of reactive functional groups—aldehyde, phenolic hydroxyl, and methoxy—which allow for selective modifications. Commonly employed in the development of agrochemicals and dyes, it also finds use in the preparation of fluorescent probes and sensors owing to its inherent fluorescence properties. Its structural features make it suitable for condensation reactions, especially in forming Schiff bases and heterocyclic compounds with biological activity.
