Description

1-Vinyl-3-(Chloromethyl)-1,1,3,3-Tetramethyldisiloxane is a specialized organosilicon compound featuring both vinyl and chloromethyl functional groups on a disiloxane backbone. This unique bifunctional structure makes it a highly versatile and valuable intermediate for the synthesis of advanced silicone polymers and hybrid materials. It is essential for manufacturers in the silicone, pharmaceutical, and advanced materials sectors seeking to create custom siloxane architectures with tailored properties.

Application

• Silicone Crosslinking Agent: Serves as a key monomer for introducing reactive sites into silicone networks, enhancing crosslink density and material properties.
• Silicone Surfactant & Modifier Precursor: Used to synthesize silicone polyether copolymers and other surfactants for polyurethane foam, coatings, and personal care products.
• Pharmaceutical Intermediate: Acts as a building block in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems that incorporate siloxane units.
• Adhesive & Sealant Formulations: Imparts improved adhesion and durability when incorporated into silicone-based adhesive and sealant products.
• Hybrid Organic-Inorganic Material Synthesis: A crucial precursor for sol-gel processes to create advanced hybrid coatings, resins, and composites with enhanced thermal and mechanical stability.
• Surface Treatment Agent: Used to modify the surface properties of inorganic materials like silica, glass, and metals for improved compatibility in composite systems.

Quality Control

Our production of 1-Vinyl-3-(Chloromethyl)-1,1,3,3-Tetramethyldisiloxane adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
