Used primarily as an intermediate in the synthesis of pharmaceuticals, especially in the production of fluorinated active pharmaceutical ingredients (APIs) where the difluoro substitution enhances metabolic stability and bioavailability. It is also employed in the preparation of agrochemicals, including herbicides and fungicides, due to the favorable electronic and lipophilic properties imparted by the fluorine atoms. Additionally, it serves as a building block in the development of liquid crystals and specialty polymers, contributing to improved thermal and chemical resistance. Its reactivity as an acyl chloride makes it suitable for coupling reactions with amines and alcohols to form amides and esters in fine chemical manufacturing.
