Used primarily as an intermediate in the synthesis of fluorinated polymers and specialty chemicals. Its reactive chlorine and fluorine groups enable cross-linking or functionalization in high-performance materials, such as heat-resistant coatings, elastomers, and membranes with enhanced chemical stability. Also employed in the development of fluorinated pharmaceuticals and agrochemicals where lipophilicity and metabolic stability are desired. The compound’s aromatic core with perfluoroalkyl substituents contributes to unique solubility and electronic properties, useful in certain electronic materials and surfactants.
