In the B2B chemical landscape, informed procurement decisions are driven by a thorough understanding of product properties. P-Styrenesulfonyl Chloride, identified by its CAS number 2633-67-2, is a critical intermediate with specific physical and chemical characteristics that dictate its application and handling. As a dedicated manufacturer and supplier, we provide clarity on these properties to assist our clients in making the best purchasing decisions.

Physically, P-Styrenesulfonyl Chloride is typically described as a yellow liquid. This physical state is important for chemists and engineers when designing handling and reaction protocols. Its molecular formula is C8H7ClO2S, and it has a molecular weight of 202.66 g/mol. The presence of the vinyl group (CH2=CH-) attached to the benzene ring, coupled with the electron-withdrawing sulfonyl chloride group (-SO2Cl), defines its chemical reactivity. The sulfonyl chloride group is highly susceptible to nucleophilic attack, making it an excellent electrophilic reagent for forming sulfonamides, sulfonate esters, and other derivatives. This reactivity is central to its use as a synthetic intermediate.

For effective procurement, understanding handling and stability is paramount. P-Styrenesulfonyl Chloride is often supplied stabilized with TBC (4-tert-butylcatechol) to inhibit premature polymerization of the vinyl group, particularly under elevated temperatures or prolonged storage. This stabilization is a key factor for ensuring product quality and safety. When you buy P-Styrenesulfonyl Chloride, it's advisable to follow the recommended storage conditions, typically in a freezer, to maintain its integrity. We, as a manufacturer, ensure these aspects are addressed in our product offerings.

The EINECS number for P-Styrenesulfonyl Chloride is 404-770-2, providing another identifier for technical documentation and regulatory compliance. Its boiling point is noted as 130 °C at 4 mmHg, and its density is around 1.32. These parameters are valuable for process design and engineering. For companies looking to purchase this intermediate, engaging with a reliable supplier like us means gaining access to accurate property data and expert advice. We facilitate the buying process by ensuring product availability and competitive pricing for P-Styrenesulfonyl Chloride (CAS 2633-67-2).
