Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for introducing the benzofuran moiety into larger structures. Commonly employed in the preparation of sulfonamide-based compounds, which are known for their antimicrobial, anti-inflammatory, and kinase inhibitory activities. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its aromatic and electron-rich furan ring system.
