Tosyl chloride

Description:
Tosyl chloride, also known as p-toluenesulfonyl chloride, is an organic compound with the chemical formula C7H7ClO2S. It is a colorless to pale yellow liquid that is highly reactive and serves as an important reagent in organic synthesis. Tosyl chloride is characterized by its sulfonyl chloride functional group, which makes it a potent electrophile, allowing it to react with nucleophiles to form tosylates. This property is particularly useful in the conversion of alcohols into better leaving groups, facilitating various substitution reactions. The compound has a strong, pungent odor and is soluble in organic solvents such as dichloromethane and ether, but is not soluble in water. Due to its reactivity, tosyl chloride must be handled with care, as it can cause severe irritation to the skin, eyes, and respiratory system. It is commonly used in the preparation of tosylate esters, which are valuable intermediates in the synthesis of pharmaceuticals and other organic compounds. Proper safety precautions, including the use of personal protective equipment, are essential when working with this chemical.

  • 4-Toluenesulfonyl chloride

    CAS:
    <p>4-Toluenesulfonyl chloride is a tosylate that reacts with amines and n-oxide groups to form sulfonamides. It is used as an antimicrobial agent and as an irreversible enzyme inhibitor. 4-Toluenesulfonyl chloride inhibits enzymes in the bowel, which may be due to its ability to form a disulfide bond with cysteine residues. This compound has been shown to have anti-cancer properties in vitro, where it inhibited the growth of carcinoma cells by inhibiting DNA synthesis. 4-Toluenesulfonyl chloride also has inhibitory properties against nitrogen atoms, which are found in the active site of many enzymes.</p>
