Description

Allyldichloromethylsilane is a highly reactive organosilicon compound characterized by its allyl and dichloromethyl functional groups. This unique structure makes it a versatile and valuable intermediate for introducing silicon-containing moieties into organic frameworks. It is primarily utilized in the synthesis of specialized silicone polymers, surface-modifying agents, and as a key building block in advanced material science. Industries involved in high-performance coatings, adhesives, and specialty chemical manufacturing will find this compound essential for developing products with tailored properties.

Application

• Silicone Polymer Synthesis: A crucial monomer or cross-linking agent for producing modified silicone resins with enhanced thermal stability and adhesion properties.
• Surface Modification: Used to functionalize inorganic surfaces (e.g., glass, silica) to improve compatibility with organic polymers in composite materials.
• Adhesives & Sealants: Serves as an intermediate in formulating high-performance, moisture-curing silicone adhesives and sealants.
• Pharmaceutical Intermediates: Acts as a key synthon in the research and development of novel silicon-containing active pharmaceutical ingredients (APIs).
• Specialty Coatings: Employed in the development of protective and release coatings that require specific surface energy and durability characteristics.
• Coupling Agents: Functions as a silane coupling agent to enhance the bond between organic polymers and inorganic fillers or reinforcements.

Quality Control

Our Allyldichloromethylsilane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including gas chromatography (GC), nuclear magnetic resonance (NMR), and Karl Fischer titration. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each 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 room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong acids, bases, and oxidizing agents.
