Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its sulfonyl chloride group readily reacts with nucleophiles like amines and alcohols, enabling the formation of sulfonamides and sulfonate esters—common motifs in drug design. It plays a significant role in developing kinase inhibitors and antimicrobial agents due to the imidazopyridine core’s favorable binding properties with biological targets. Also employed in combinatorial chemistry for generating compound libraries in medicinal research.
