For professionals in the chemical, pharmaceutical, and agrochemical sectors, understanding the properties and applications of key intermediates is crucial for effective procurement and research. Benzylsulfonyl Chloride, designated by CAS number 1939-99-7, is a significant fine chemical intermediate, widely recognized for its role in various synthetic processes. This article provides an in-depth look at Benzylsulfonyl Chloride, covering its physical and chemical characteristics, safety considerations, and application spectrum, with a focus on why sourcing from a reputable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is advantageous.

Benzylsulfonyl Chloride typically presents as a white crystalline powder and boasts a high purity, often specified at 98% or higher by GC. This level of purity is essential for ensuring consistent reaction outcomes in sensitive applications such as pharmaceutical synthesis and advanced agrochemical formulation. The compound’s molecular formula, C7H7ClO2S, and its reactive sulfonyl chloride group make it a versatile building block for creating complex organic molecules. Its solubility in common organic solvents like dichloromethane and ether, while being largely insoluble in water, dictates its handling and reaction conditions.

Handling Benzylsulfonyl Chloride requires adherence to strict safety protocols. As a reactive chemical, it is corrosive and can cause severe irritation to skin, eyes, and the respiratory tract. Proper personal protective equipment (PPE), including gloves, safety goggles, and a lab coat, is mandatory. Adequate ventilation in the workspace is also critical to minimize inhalation risks. Due to its sensitivity to moisture, it should be stored in tightly sealed containers in a cool, dry environment, away from incompatible materials such as strong bases and oxidizing agents. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive safety data sheets (SDS) to guide users on safe handling and storage practices.

The primary applications for Benzylsulfonyl Chloride lie in its use as an intermediate in the pharmaceutical and agrochemical industries. It is instrumental in the synthesis of sulfonamides, which are core structures in many drugs and pesticides. Researchers and procurement managers seeking to buy Benzylsulfonyl Chloride should consider its specific role in their synthesis pathways. Whether for introducing sulfonyl groups, protecting amine functionalities, or as a reagent in specific coupling reactions, its consistent purity ensures predictable results.
