Description

(Dichloromethyl)Methyldichlorosilane is a highly reactive organosilicon compound primarily used as a key synthetic intermediate. Its value lies in its ability to introduce functional silane groups into target molecules, enabling the creation of advanced silicone polymers and specialty chemicals. This product is essential for manufacturers in the silicone industry, particularly for those developing high-performance materials, surface modifiers, and custom silane coupling agents.

Application

• Silicone Polymer Synthesis: A crucial monomer or intermediate in the production of specialized methylchlorosilane-based polymers and resins.
• Surface Modification Agent: Used to functionalize inorganic surfaces like glass, silica, or metals to alter their hydrophobicity, adhesion, or compatibility with organic matrices.
• Silane Coupling Agent Precursor: Serves as a starting material for synthesizing custom silane coupling agents used in composite materials, adhesives, and sealants.
• Pharmaceutical & Agro-chemical Intermediates: Employed in the synthesis of complex molecules where the introduction of a specific chlorosilane functionality is required.
• Laboratory Reagent: Used in research and development for organometallic chemistry and novel material science applications.

Quality Control

Our (Dichloromethyl)Methyldichlorosilane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through analytical methods including Gas Chromatography (GC) and titration. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with every shipment to guarantee it meets your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, fluorides, and sources of ignition. Due to its highly volatile nature, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent moisture ingress and decomposition. Recommended storage temperature is 2-8°C.
