Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active compounds for therapeutic applications. Its trifluoromethyl group enhances the biological activity and metabolic stability of the resulting molecules. Commonly employed in the preparation of agrochemicals, where it contributes to the creation of pesticides and herbicides with improved efficacy. Also utilized in organic synthesis for constructing complex molecules due to its reactive aldehyde group and electron-withdrawing substituents, which facilitate various chemical transformations.
