Product Name:4-Methylbenzylsulfonyl chloride
English Name:4-Methylbenzylsulfonyl chloride
CAS No.:51419-59-1
Aliases:p-Methylbenzylsulfonyl chloride, 4-Methylphenylmethanesulfonyl chloride, (4-Methylphenyl)methanesulfonyl chloride, p-Tolylmethanesulfonyl chloride
Molecular Formula:C8H9ClO2S
Physical Properties:Colorless to pale yellow transparent liquid or low-melting solid with a pungent odor. Molecular weight 204.67, relative density approximately 1.25 g/mL at 25 °C, boiling point approximately 130–135 °C at 0.5 mmHg (with decomposition), flash point approximately 110 °C. Freely soluble in organic solvents such as dichloromethane, chloroform, ethyl acetate and ether; decomposes slowly upon contact with water or alcohols, requiring dry and sealed storage in a cool place protected from light.
Uses:Used as an intermediate in organic synthesis, primarily serving as a sulfonylating reagent to prepare sulfonamide derivatives by reaction with amines and sulfonate esters by reaction with alcohols. Widely applied in the synthesis of pharmaceuticals, agrochemicals and fine chemicals.
Technical Specifications:
Purity ≥ 98% (GC)
Appearance: colorless to pale yellow transparent liquid or low-melting solid
Formula: C8H9ClO2S, molecular weight: 204.67
Relative density approximately 1.25 g/mL at 25 °C
