Used as a key intermediate in the synthesis of agricultural chemicals, particularly herbicides and insecticides, due to its reactive aldehyde group and electron-withdrawing substituents that enhance its utility in coupling reactions. It is also employed in the production of pharmaceuticals, where it serves as a building block for active ingredients targeting inflammatory and central nervous system disorders. Its trifluoromethyl and chloro groups contribute to improved metabolic stability and bioavailability in final drug compounds. Additionally, it finds use in the development of dyes and functional materials where aromatic aldehydes with halogen substituents are required for specific electronic properties.
