Introduction:

Benzene Sulphonyl Chloride, commonly known as BSC, is a colorless, volatile liquid with a mild aromatic odor. It is also called benzene sulphonic chloride or sulfonyl chloride, derived from benzoic acid and SO2.

It is one of the isocyanates and is used in the production of biocides. The reaction of benzene and isocyanate produces it. It is soluble in water and ethanol.

It is also very reactive and can form explosive compounds when combined with other chemicals or substances.

This chemical reacts with air readily, which produces the flammable gas benzoic acid. It reacts violently with water to form hydrogen chloride and benzene.

Applications:

Benzene sulphonyl chloride is a chemical compound and is mainly used in the pharmaceutical and agrochemical industry. It is used in the production of pesticides and pharmaceuticals. It can use it to produce plastics such as polystyrene and Styrofoam. It's also used to make foams for mattresses, cushions, and pillows. It is used in the production of detergents, pesticides, plasticizer resins, and dyes. Benzene sulphonyl chloride is used for preparing cephalosporin antibiotics. One standard method for preparing cephalosporin is the chemical reaction of it with 7-aminocephalosporanic acid. It is used as an intermediate for dyes and pigments and as a chemical reagent and solvent.
