Description

Dichloro(2-Methoxyethyl)Methylsilane is a versatile organosilicon compound characterized by its reactive chlorosilane and ether-functional side chain. This bifunctional nature makes it a valuable intermediate for introducing silicon-containing moieties with enhanced solubility and compatibility into polymer backbones and surface coatings. It is primarily sought after by R&D chemists and process engineers in the advanced materials, electronics, and specialty chemical synthesis sectors for developing novel silicones, adhesion promoters, and surface-modifying agents.

Application

• Silicone Polymer Modification: Serves as a key monomer or cross-linking agent for synthesizing specialty silicone resins and elastomers with tailored properties.
• Surface Treatment & Coupling Agent: Used to functionalize inorganic surfaces (glass, silica, metals) to improve adhesion and compatibility with organic polymers in composite materials.
• Electronic Materials Precursor: Employed in the production of spin-on-glass (SOG) dielectrics, insulating coatings, and passivation layers in semiconductor manufacturing.
• Hydrophobic Coating Formulations: Acts as a building block for creating water-repellent and anti-corrosive coatings for textiles, construction materials, and optical components.
• Pharmaceutical & Agro-Intermediate Synthesis: Utilized as a protected or functionalized synthon in the multi-step synthesis of complex bioactive molecules.
• Adhesive & Sealant Additive: Enhances the moisture-curing characteristics, flexibility, and bonding strength of silicone-based adhesives and sealants.

Quality Control

Our production of Dichloro(2-Methoxyethyl)Methylsilane adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and Karl Fischer titration. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (nitrogen or argon) when not in use. Keep away from strong acids, bases, and oxidizing agents.
