Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals. Its sulfonyl chloride group readily reacts with nucleophiles like amines and alcohols, making it valuable for constructing sulfonamide or sulfonate ester linkages. Commonly employed in the development of protease inhibitors and other therapeutic agents where chromane scaffold enhances metabolic stability. Also utilized in agrochemical synthesis for building complex molecules with improved efficacy and selectivity.
