Description

Diethylmethylvinylsilane is a versatile organosilicon compound characterized by its reactive vinyl group and two ethyl substituents. This structure makes it a valuable intermediate for introducing silicon-containing functional groups into polymers and other advanced materials. It is primarily utilized in the synthesis of silicone polymers, surface modification agents, and as a key building block in organometallic chemistry. Industries involved in specialty chemicals, advanced material science, and pharmaceutical intermediates will find this compound essential for their R&D and production processes.

Application

• Silicone Polymer Synthesis: Serves as a crucial monomer or cross-linking agent in the production of vinyl-functionalized silicones and silicone elastomers.
• Surface Modification: Used to create hydrophobic or oleophobic coatings on glass, metals, and ceramics via hydrosilylation or other coupling reactions.
• Adhesive & Sealant Formulations: Imparts improved adhesion and flexibility as a reactive modifier in high-performance silicone-based adhesives and sealants.
• Pharmaceutical Intermediates: Acts as a protected silicon reagent in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Research & Development: Employed in academic and industrial labs for developing new organosilicon compounds and studying reaction mechanisms.
• Electronics & Semiconductor Industry: Used in the deposition of silicon-containing thin films and as a precursor in chemical vapor deposition (CVD) processes.

Quality Control

Our Diethylmethylvinylsilane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing identity, purity, and physical properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (36-46°F) to maximize shelf life and stability.
