4-Methylbenzenesulfonyl fluoride(CAS: 455-16-3)

4-Methylbenzenesulfonyl fluoride (CAS: 455-16-3) is a white crystalline solid with a molecular weight of approximately 195.15 g/mol. It is slightly soluble in water but more soluble in organic solvents such as ethanol and acetone. This compound is highly reactive and prone to hydrolysis, decomposing to form a mixture of 4-methylbenzenesulfinic acid and 4-methylbenzene sulfonic acid under basic conditions.

4-Methylbenzenesulfonyl fluoride (CAS: 455-16-3) is typically synthesized by the reaction of 4-methylbenzenesulfonyl chloride with hydrogen fluoride. This process is carried out in a solvent such as methylene chloride, with a yield of around 85%. The reaction is selective and proceeds without the need for a catalyst.

4-Methylbenzenesulfonyl fluoride (CAS: 455-16-3) is used in the pharmaceutical industry for the synthesis of certain drug intermediates. It is also utilized in the polymer industry for the preparation of functionalized polymers, and in the electronics industry for the fabrication of semiconductor materials and sensors due to its reactivity and stability.

When handling 4-Methylbenzenesulfonyl fluoride (CAS: 455-16-3), it is crucial to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. This compound should be handled in a well-ventilated area or within a fume hood to minimize inhalation risk. Spills should be cleaned up carefully following standard laboratory procedures, and the material safety data sheet (MSDS) or safety data sheet (SDS) should be consulted for detailed spill handling instructions.
