Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for constructing sulfonamide and sulfonate ester derivatives. Commonly employed in the development of active ingredients in crop protection agents and medicinal compounds, especially where fluorine substitution enhances metabolic stability or binding affinity. Its methyl and fluoro substituents allow for further functionalization, enabling fine-tuning of molecular properties in drug design.
