Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and bioactive compounds. Its structure supports the construction of nitrogen-containing heterocycles, which are common in crop protection agents and medicinal chemistry. The aldehyde group allows for condensation reactions, enabling the formation of imines or other derivatives useful in drug discovery. It is also employed in the preparation of selective kinase inhibitors and pesticidal agents due to the electron-withdrawing nature of the trifluoromethyl and chloro substituents, which enhance metabolic stability and binding affinity.
