Description

2-(Chloromethyl)Allyltrichlorosilane is a highly reactive organosilicon compound featuring both chloromethyl and trichlorosilyl functional groups on an allylic backbone. This unique structure makes it a versatile and critical intermediate for introducing silicon-containing moieties into polymer chains and organic molecules. It is primarily sought after by R&D chemists and process engineers in the specialty chemical and advanced materials sectors for synthesizing custom silanes, modifying surfaces, and developing novel polymeric materials.

Application

• Synthesis of Functional Silanes: Serves as a key building block for creating custom organosilicon coupling agents with specific reactive end groups.
• Polymer Modification: Used to incorporate reactive chloromethyl and silyl groups into polymer backbones, enhancing properties like adhesion, cross-linking capability, or providing sites for further functionalization.
• Surface Pretreatment & Coatings: Applied in the formulation of primers and adhesion promoters for metals, glass, and minerals, improving the bonding of subsequent layers.
• Intermediate for Silicone Chemistry: Acts as a precursor in the production of specialized silicone oils, resins, and elastomers with tailored properties.
• Research & Development: Utilized in academic and industrial R&D for exploring new organosilicon compounds, dendrimers, and hybrid organic-inorganic materials.

Quality Control

Our production of 2-(Chloromethyl)Allyltrichlorosilane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and titration methods, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications and confirming compliance with agreed-upon standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. 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. Recommended storage temperature is 2-8°C for extended stability.
