Used primarily as an intermediate in the synthesis of pharmaceuticals, especially in the development of fluorinated organic compounds with enhanced metabolic stability and bioavailability. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for constructing sulfonamide and sulfonate ester derivatives in drug discovery. Commonly employed in the preparation of kinase inhibitors and other biologically active molecules where the fluorine and ethoxy substituents fine-tune electronic and steric properties. Also utilized in agrochemical synthesis for building herbicidal and insecticidal agents.
