Description

Allyl(Chloromethyl)Dimethylsilane CAS NO 33558-75-7 is a versatile organosilicon compound featuring both an allyl group and a reactive chloromethyl functionality. This dual reactivity makes it a valuable intermediate for the synthesis of specialized silicone polymers, cross-linking agents, and surface modifiers. It is primarily sought after by manufacturers in the silicone elastomer, adhesive, and advanced materials sectors for developing products with tailored properties.

Application

• Silicone Polymer Modification: Acts as a key monomer or cross-linker for introducing allyl and chloromethyl groups into silicone backbones, enhancing properties like adhesion and reactivity.
• Adhesive & Sealant Formulations: Used to synthesize functional silanes that improve the bonding performance of silicone-based adhesives and sealants to various substrates.
• Surface Treatment Agent: Serves as a precursor for creating hydrophobic or chemically reactive coatings on glass, metals, and minerals.
• Pharmaceutical & Agro-chemical Intermediates: Employed in the synthesis of complex molecules where the silane moiety is incorporated for specific biological activity or delivery mechanisms.
• Specialty Resin Synthesis: Utilized in the production of high-performance resins with enhanced thermal stability and chemical resistance.
• Research & Development: A valuable building block in organic and organometallic chemistry research for constructing novel silicon-containing compounds.

Quality Control

Our Allyl(Chloromethyl)Dimethylsilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC and NMR, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, and open flame.
