Description

Chloro(Chloromethyl)Dimethylsilane is a highly reactive bifunctional organosilicon compound that serves as a critical building block in advanced material synthesis. Its dual functionality, featuring both a chloromethyl and a chloro group, makes it an exceptionally versatile intermediate for introducing silicon-containing moieties into polymer backbones and surfaces. This product is essential for R&D and production teams in the specialty chemical, pharmaceutical, and advanced materials sectors seeking to develop novel silane coupling agents, functional polymers, and surface modifiers.

Application

• Silane Coupling Agent Precursor: A key intermediate for synthesizing specialized silane coupling agents used to improve adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Polymer Modification: Employed to introduce reactive chloromethyl and chlorosilane groups into polymer chains, enabling further functionalization for creating ion-exchange resins, specialty coatings, and membranes.
• Surface Functionalization: Used to modify the surface properties of silica, nanoparticles, and other substrates to impart specific chemical reactivity or compatibility.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of organosilicon compounds with potential biological activity or for drug delivery system development.
• Cross-linking Agent: Acts as a cross-linker in the production of silicone resins and elastomers with enhanced thermal and chemical resistance.
• Hydrophobic Coating Formulations: A starting material for creating water-repellent and corrosion-resistant coating additives.

Quality Control

Our Chloro(Chloromethyl)Dimethylsilane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) for assay and impurity profiling. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as purity, identity, and specific impurities. Our quality management system supports compliance with relevant global chemical regulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
