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 sulfonamides and sulfonate esters—key motifs in drug design. It is especially useful in the development of bioactive molecules where the difluoro and methyl substituents enhance metabolic stability and binding selectivity. Commonly employed in medicinal chemistry for the preparation of enzyme inhibitors and receptor modulators. Also utilized in the manufacture of specialty chemicals requiring high reactivity and specific electronic properties.
