In the vast landscape of specialty chemicals, organosilicon compounds hold a significant place due to their unique properties and diverse applications. Vinyldimethylchlorosilane (CAS 1719-58-0) is one such compound that serves as a vital intermediate in numerous industrial processes. For procurement managers and chemical engineers, a thorough understanding of its characteristics, applications, and sourcing dynamics is essential for efficient operations.

Physical and Chemical Properties of Vinyldimethylchlorosilane

Vinyldimethylchlorosilane is readily identifiable as a colorless, transparent liquid. Its key chemical features include a vinyl group attached to a silicon atom, which also bears two methyl groups and a chlorine atom. This structure imparts significant reactivity. The Si-Cl bond is prone to hydrolysis, reacting readily with moisture and protic solvents, a characteristic that necessitates careful handling and storage under inert conditions. Its typical purity is high, often exceeding 98%, which is critical for its role in synthesis. Key physical properties include a boiling point around 82-83°C and a density of approximately 0.874 g/mL at 25°C. These properties influence its handling, storage, and reaction parameters.

Primary Applications in Industry

The industrial utility of Vinyldimethylchlorosilane is primarily centered around its use as an intermediate in the synthesis of silicone-based materials. These include:

  • Silicone Oils: It is a precursor for various silicone fluids, which are used as lubricants, dielectric fluids, and cosmetic ingredients.
  • Silicone Rubbers: It plays a crucial role in the polymerization and cross-linking processes that create silicone elastomers. These elastomers find applications in seals, gaskets, medical devices, and electrical insulation due to their excellent thermal stability and flexibility.
  • Other Organosilicon Compounds: It serves as a versatile building block for synthesizing a range of functional silanes and organosilicon intermediates used in specialized applications like coupling agents and surface modifiers.

Sourcing Vinyldimethylchlorosilane: Suppliers and Pricing Insights

When looking to buy Vinyldimethylchlorosilane, identifying a reliable supplier is a critical step. Many businesses opt to source from manufacturers in China, which often offer competitive pricing and substantial production capacities. It is important for buyers to conduct due diligence on potential suppliers, verifying their quality control processes and product consistency. Requesting technical data sheets (TDS) and safety data sheets (SDS) is standard practice.

The price of Vinyldimethylchlorosilane can vary based on factors such as purity, order volume, and global market conditions. For procurement managers, obtaining multiple quotes from different suppliers is a recommended approach to secure the best possible terms. For instance, companies like NINGBO INNO PHARMCHEM CO.,LTD. are recognized for their supply of high-quality chemical intermediates, including Vinyldimethylchlorosilane. Establishing a relationship with such a manufacturer can ensure a stable and cost-effective supply chain.

In conclusion, Vinyldimethylchlorosilane is a fundamental chemical intermediate with broad applications in silicone chemistry. By understanding its properties, applications, and the nuances of sourcing, businesses can optimize their procurement strategies and ensure the consistent availability of this vital compound for their manufacturing needs.
