Phenylmethanesulfonyl chloride(CAS: 1939-99-7)

Phenylmethanesulfonyl chloride (CAS: 1939-99-7) is a chemical compound with the molecular formula C8H7O3SCl. It is a white solid and is used as a protecting group in organic synthesis, particularly for sulfonic acid groups.

Phenylmethanesulfonyl chloride is primarily used as a reagent in organic synthesis for the protection of sulfonic acid groups. It is also utilized in pharmaceuticals and chemical research for making derivatives of sulfonic acids and sulfonamides.

Phenylmethanesulfonyl chloride is not considered highly toxic, but it is corrosive and may cause skin and eye irritation. It should be handled with appropriate personal protective equipment (PPE) such as gloves and goggles. Storage and use should be in a well-ventilated area, and all safety data sheets (SDS) should be consulted for detailed safety information.

Phenylmethanesulfonyl chloride should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a tightly sealed container to prevent moisture absorption. The storage temperature should not exceed 25°C (77°F) to ensure stability and prevent degradation.
