Description

Bis(Dimethylamino)Methylvinylsilane is a highly reactive organosilicon compound that serves as a versatile precursor and coupling agent in advanced material synthesis. Its unique bifunctional structure, featuring both dimethylamino and vinyl groups, enables it to act as a key intermediate for introducing silicon-containing moieties into polymer backbones and inorganic matrices. This product is essential for R&D and production teams in the silicone polymer, specialty coatings, and electronics industries seeking to modify surface properties or create hybrid organic-inorganic materials.

Application

• Silicone Polymer Modification: Used as a functional monomer or cross-linking agent in the synthesis of specialty silicone elastomers and resins, imparting tailored mechanical and thermal properties.
• Surface Treatment & Adhesion Promotion: Acts as a coupling agent for glass, minerals, and metals to improve the adhesion of polymers and coatings to inorganic substrates.
• Precursor for Silicone-Based Materials: Serves as a critical intermediate in the production of silanes, siloxanes, and other organosilicon compounds for electronics and release coatings.
• Pharmaceutical & AgroChemical Intermediates: Utilized in the synthesis of silicon-containing active ingredients or prodrugs where the silicon center modifies bioavailability.
• Sol-Gel Chemistry: Employed in the preparation of hybrid organic-inorganic materials and nanocomposites for optical, electronic, or protective coating applications.
• Research & Development: A valuable building block in academic and industrial R&D for exploring new silicon chemistry, catalysis, and material science.

Quality Control

Our Bis(Dimethylamino)Methylvinylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Keep away from heat, sparks, and open flame. Due to its highly volatile and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (nitrogen or argon) after opening.
