4-chlorobenzenesulfinic acid

Description:
4-Chlorobenzenesulfinic acid, with the CAS number 100-03-8, is an aromatic sulfonic acid characterized by the presence of a sulfinic acid group (-SO2H) attached to a chlorinated benzene ring. This compound typically appears as a white to light yellow crystalline solid and is soluble in water and organic solvents. Its structure features a chlorine atom at the para position relative to the sulfinic acid group, which influences its reactivity and properties. 4-Chlorobenzenesulfinic acid is known for its utility in organic synthesis, particularly as a reagent in the preparation of various sulfonamides and other derivatives. It exhibits moderate acidity due to the sulfinic acid functional group, which can participate in proton transfer reactions. Additionally, this compound can act as a reducing agent and is used in dye manufacturing and as an intermediate in the synthesis of pharmaceuticals. Safety precautions should be observed when handling this substance, as it may cause irritation to the skin and eyes.
