In the intricate world of pharmaceutical manufacturing, the reliability and quality of raw materials are paramount. For procurement managers and R&D scientists, identifying trusted suppliers for key chemical intermediates is a constant priority. One such vital intermediate is Benzene Sulfenyl Chloride, identified by its CAS number 931-59-9. Understanding its properties and applications is crucial for making informed purchasing decisions.

Benzene Sulfenyl Chloride, also known by its other names like phenyl thiohypochlorite or benzenesulfenyl chloride, is a highly reactive organic compound. Its chemical formula is C6H5ClS, with a molecular weight of 144.622. Typically appearing as a white solid with a melting point of 44°C, it is a stable compound under normal conditions, which is advantageous for storage and handling. As a leading manufacturer and supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. ensures our Benzene Sulfenyl Chloride meets a minimum purity of 99%, a specification that is critical for its use in sensitive pharmaceutical synthesis pathways.

The primary utility of Benzene Sulfenyl Chloride lies in its role as a benzene sulfonium reagent. It is extensively used in organic synthesis for the preparation of a wide array of compounds. Notably, it is instrumental in the synthesis of optically active compounds. For instance, it facilitates the addition reaction with olefins and alkynes to prepare β-chlorinated alkyl phenyl sulfides and alkenyl phenyl sulfides, respectively. These reactions are fundamental in building complex molecular architectures required for novel drug candidates.

Furthermore, Benzene Sulfenyl Chloride plays a significant role in the formation of various heterocyclic compounds. It can react with α,β-unsaturated amides to produce five- and six-membered rings, such as pyrrolidine and piperidine rings, which are common structural motifs in many pharmaceuticals. It is also employed in reactions with diazo compounds to yield α,β-unsaturated ketones and in the stereoselective synthesis of olefins and terpenes. When looking to buy this essential chemical, understanding these diverse applications helps in appreciating its value to your R&D pipeline.
