The world of chemical intermediates is vast, with many compounds serving as critical linchpins in the creation of advanced materials. Among these, VINYLPHENYLDICHLOROSILANE (CAS 7719-02-0) holds a significant position in the organosilicon sector. Its unique combination of a vinyl group, a phenyl ring, and reactive chlorine atoms attached to a silicon center makes it a versatile reagent for chemists and material scientists. Understanding its chemistry, properties, and how to source it effectively from manufacturers is vital for those pushing the boundaries of material innovation.

VINYLPHENYLDICHLOROSILANE is characterized by its formula C8H8Cl2Si and a molecular weight of 203.14. As a clear liquid, it possesses a melting point of -43°C and a boiling point of approximately 84-87°C at reduced pressure. Its density is around 1.196 g/mL, and its refractive index is 1.5322. The presence of two chlorine atoms bonded to silicon renders it highly reactive towards moisture and protic solvents, a characteristic common to many chlorosilanes. This reactivity is precisely what makes it valuable; the chlorine atoms can be easily substituted by various nucleophiles, allowing for the attachment of different organic or inorganic moieties. The vinyl group, on the other hand, enables participation in polymerization reactions, such as free-radical polymerization or hydrosilylation, making it an excellent monomer or cross-linker.

The applications of VINYLPHENYLDICHLOROSILANE are diverse, primarily within the synthesis of specialty polymers and functional materials. It serves as a precursor for developing silicone resins with enhanced thermal stability and mechanical properties, owing to the phenyl group's contribution. It's also instrumental in creating silane coupling agents, which are essential for improving the adhesion between organic polymers and inorganic fillers in composite materials. For example, by reacting VINYLPHENYLDICHLOROSILANE with appropriate functional groups on fillers, a strong interfacial bond can be formed, leading to composites with superior strength and durability. Researchers and manufacturers looking to buy this compound will find its use critical in creating advanced coatings, adhesives, and sealants with tailored performance characteristics.

Procurement managers and purchasing agents should consider several factors when looking to buy VINYLPHENYLDICHLOROSILANE. Sourcing from reputable manufacturers, especially those in China, can offer competitive VINYLPHENYLDICHLOROSILANE prices and ensure consistent product quality, often at 95% purity. It's important to obtain a detailed Certificate of Analysis (CoA) to verify purity and other critical parameters. Understanding the typical cost implications based on order volume is also key to effective budgeting. Establishing a relationship with a reliable supplier ensures a stable supply chain, which is crucial for ongoing manufacturing processes.

In essence, VINYLPHENYLDICHLOROSILANE (CAS 7719-02-0) is a cornerstone chemical intermediate that unlocks new possibilities in material science. Its unique reactivity and structural features make it indispensable for synthesizing advanced organosilicon materials. By understanding its chemical nature and strategically sourcing it from reliable manufacturers, businesses can leverage this compound to innovate and excel in their respective fields.
