Description

Vinylphenyldichlorosilane is a highly reactive organosilicon compound characterized by its vinyl and phenyl functional groups attached to a silicon dichloride core. This dual functionality makes it a critical intermediate for introducing both hydrophobic phenyl groups and polymerizable vinyl groups into silicone-based materials. It is essential for manufacturers in the advanced materials sector seeking to create custom silane coupling agents, specialized silicone resins, and high-performance polymer precursors. The compound, identified by CAS number 7719-02-0, is primarily utilized in R&D and production of materials requiring tailored surface properties and cross-linking capabilities.

Application

• Silane Coupling Agent Precursor: Serves as a key starting material for synthesizing vinyl- and phenyl-containing silane coupling agents used to improve adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Silicone Resin & Polymer Modification: Used to incorporate phenyl groups into silicone polymers, enhancing their thermal stability, radiation resistance, and compatibility with organic materials.
• Cross-linking Agent for Silicones: The vinyl group enables participation in hydrosilylation reactions, making it valuable for creating cross-linked silicone networks in elastomers, gels, and coatings.
• Surface Treatment & Functionalization: Applied in the surface modification of silica, quartz, and other fillers to impart organophilic characteristics and improve dispersion in polymer matrices.
• Intermediate for Specialty Chemicals: Acts as a versatile building block in organic synthesis for pharmaceuticals, agrochemicals, and liquid crystal materials where specific silicon-containing architectures are required.
• Adhesive & Sealant Formulations: Contributes to the development of high-performance adhesives and sealants with improved flexibility, water repellency, and durability.

Quality Control

Our Vinylphenyldichlorosilane is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment. We adhere to relevant industry standards and can support compliance requirements for research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Incompatible with strong bases, strong acids, and oxidizing agents. Recommended storage temperature: 2-8°C for long-term stability.
