About Para Toluenesulfonyl Chloride

p-Toluene sulphonyl chloride, 98% Cas 98-59-9 - used in organic synthesis.T 1905 (OTTO) p-Toluene sulphonyl chloride, 98% Cas 98-59-9 - used as a precursor in the production of dyes and saccharin. It acts as a dehydrating agent in the conversion of urea to carbodiimide and converts alcohols into the corresponding toluenesulfonate esters. It is also employed as a flow-promoting agent for paints, an adhesive, nitrocellulose, coating material and as a plasticizer for polyamides.

Key Physical and Chemical Properties

Para Toluenesulfonyl Chloride is a solid with a molecular formula of C7H7ClO2S and a molecular weight of 190.65 g/mol. It is soluble in organic solvents such as chloroform, benzene, and ether, but insoluble in water. The compound is stable when stored in a cool, dry, well-ventilated area, tightly sealed to prevent hydrolysis. Melting point ranges from 68-70C, and it decomposes at higher temperatures during boiling.


Applications in Industry

This compound serves as an important intermediate in pharmaceutical development, dye and pigment production, and organic synthesis. Its high purity and reactivity make it ideal for facilitating key chemical transformations. It is chosen for its reliability in creating sulfonyl derivatives and other complex molecules, contributing to advancements in medicinal and industrial chemistry.


Safe Storage and Handling Recommendations

Para Toluenesulfonyl Chloride requires careful storage away from moisture and incompatible substances to maintain stability. Containers should remain tightly sealed; open packages must be handled quickly and under controlled conditions. Always use protective gear due to its corrosive and reactive nature. Adhering to transport regulations (UN 3261, Class 8) is crucial for safety during transit.
