Used in the synthesis of pharmaceutical intermediates, particularly in the production of anticoagulant and anti-inflammatory drugs. Acts as a building block in organic synthesis due to the presence of both aldehyde and carboxylic acid functional groups, enabling diverse derivatization reactions. Employed in the preparation of dyes and photo-sensitive materials for imaging applications. Also utilized in the development of agrochemicals, where it serves as a precursor for herbicides and plant growth regulators. Its methoxy and formyl groups facilitate coupling reactions in the formation of complex aromatic structures.
