Phenyl Chlorothionocarbonate, identified by CAS number 1005-56-7, is a chemical compound with specific physical and chemical properties that dictate its utility and handling in industrial and laboratory settings. As a fundamental intermediate in organic chemistry, a comprehensive understanding of its characteristics is crucial for chemists, manufacturers, and anyone involved in its procurement or application. This insight not only ensures effective utilization but also promotes safe practices.

Physically, Phenyl Chlorothionocarbonate presents as a clear yellow liquid. Its molecular formula is C7H5ClOS, and it has a molecular weight of approximately 172.63 g/mol. Key physical properties include a density of around 1.248 g/mL at 25°C and a refractive index of n20/D 1.581. The compound is sensitive to moisture, indicating that proper storage under dry, inert conditions is essential to maintain its integrity and reactivity. Its solubility in common organic solvents like chloroform and ethyl acetate further facilitates its use in various reaction mediums.

The synthesis of Phenyl Chlorothionocarbonate typically involves reactions with specific sulfur and chlorine-containing precursors. While the exact industrial preparation methods may vary among manufacturers, the goal is always to achieve high purity, often exceeding 98%. The chemical reactivity of Phenyl Chlorothionocarbonate stems from its thiocarbonyl chloride functional group, which readily participates in nucleophilic substitution and addition reactions. This reactivity is precisely what makes it a valuable intermediate for creating more complex molecules.

Safety is a critical consideration when handling Phenyl Chlorothionocarbonate. It is classified as a corrosive substance (Hazard Class 8) and is designated UN 3265, Packing Group II. This classification necessitates strict adherence to safety protocols, including working in well-ventilated areas or fume hoods, and wearing appropriate personal protective equipment such as gloves, safety glasses, and protective clothing. Its sensitivity to moisture also implies that storage should be in tightly sealed containers under an inert atmosphere, away from incompatible materials.

For companies looking to buy Phenyl Chlorothionocarbonate, understanding these chemical properties and safety guidelines is as important as selecting a reputable supplier. Access to detailed technical data sheets (TDS) and Material Safety Data Sheets (MSDS) from manufacturers is vital for safe and effective handling. By prioritizing these aspects, chemical industry professionals can ensure the successful and responsible use of this important synthetic intermediate.
