Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and bioactive molecules. Its structure supports the creation of compounds with enhanced metabolic stability and binding affinity. Commonly employed in the preparation of herbicides and fungicides due to the presence of halogen and trifluoromethyl groups, which improve lipophilicity and environmental persistence. Also utilized in medicinal chemistry for constructing nitrogen-containing heterocycles with potential therapeutic activity.
