Description

Dimethylvinylsilane is a highly reactive organosilicon compound characterized by its vinyl functional group. This compound matters as a versatile and critical building block in organosilicon chemistry, enabling the introduction of both silicon and reactive vinyl moieties into target molecules. It is essential for manufacturers and R&D teams in the silicone polymer, specialty chemical, and advanced materials sectors seeking to create cross-linked networks, functional coatings, or novel silicon-based monomers.

Application

• Key monomer for the synthesis of vinyl-functional silicone polymers and resins.
• Cross-linking agent in the production of heat-cured silicone rubbers and elastomers.
• Intermediate in the manufacture of silane coupling agents for surface modification.
• Precursor for hydrosilylation reactions to create custom organosilicon compounds.
• Raw material for specialty adhesives, sealants, and release coatings.
• Building block in R&D for advanced materials, including ceramics and composites.
• Used in the synthesis of silicon-containing dendrimers and other macromolecules.

Quality Control

Our Dimethylvinylsilane 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. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area, away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, it is recommended to keep the container tightly sealed and use shortly after opening. Recommended storage temperature is 2-8°C for long-term stability.
