Description and Uses

4-Chloro-3-nitrobenzenesulfonyl chloride can be used:

• In the preparation of functionalized 1H-indenes via copper-catalyzed arylative cyclization.
• As a precursor in the synthesis of N-arylsulfonyl-3-acylindole arylcarbonyl hydrazone derivatives that show potential nematicidal activity.
• As a key starting material in the synthesis of sulfonamide analogs of ferrostatin-1 (fer-1), which possess good ferroptosis inhibition property.
• In the synthesis of 4-chloro-3-nitrobenzene thiol.
