Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. Its electrophilic aldehyde group and halogenated aromatic structure make it valuable for constructing complex organic molecules through condensation, reduction, or nucleophilic substitution reactions. Commonly employed in the preparation of active ingredients in crop protection agents due to the enhanced stability and bioactivity imparted by the trifluoromethyl and chloro substituents. Also utilized in research for the development of novel organic compounds with potential biological activity.
