4-Iodobenzenesulfonyl chloride（Cat No.:L011416）is an electrophilic reagent used primarily in organic synthesis for sulfonamide and sulfonate ester formation. Featuring both a reactive sulfonyl chloride group and an iodine atom on a para-substituted benzene ring, it serves as a versatile intermediate for introducing sulfonyl groups and for further functionalization via cross-coupling reactions like Suzuki or Sonogashira. Its dual reactivity allows it to participate in multistep synthesis of pharmaceuticals, agrochemicals, and advanced materials. The compound is typically handled under dry conditions due to its sensitivity to moisture and hydrolysis.
