Description

2-(Carbomethoxy)Ethylmethyldichlorosilane is a highly reactive organosilicon compound, specifically a chlorosilane ester, that serves as a critical building block in advanced material synthesis. Its molecular structure, featuring both a hydrolyzable dichlorosilane group and a protected carbomethoxyethyl chain, makes it an exceptionally versatile intermediate for introducing specific functional groups onto silicon-based backbones. This compound is essential for manufacturers and R&D teams in the silicone polymers, surface modification, and specialty chemical sectors who require precise molecular control to develop products with tailored properties such as adhesion, release, or chemical resistance.

Application

• Silicone Polymer Modification: A key monomer for synthesizing custom polysiloxanes and silicone copolymers with pendant ester-functional groups.
• Surface Coupling Agent: Used to modify inorganic surfaces (glass, silica, metals) to improve adhesion with organic polymers or to create specific surface energies.
• Intermediate for Silane Coupling Agents: Serves as a precursor in the production of advanced bifunctional silanes used in composite materials, adhesives, and sealants.
• Pharmaceutical & Agrochemistry Intermediates: Employed in the synthesis of silicon-containing active ingredients or protecting groups in complex organic syntheses.
• Hydrophobic Coating Formulations: Imparts water-repellent characteristics to surfaces in protective coating applications.
• Research & Development: A valuable tool in academic and industrial labs for exploring new organosilicon chemistry and material science applications.

Quality Control

Every batch of 2-(Carbomethoxy)Ethylmethyldichlorosilane is produced and tested under a strict quality management system. We ensure product integrity through comprehensive analytical methods including GC, NMR, and titration to verify identity, purity, and absence of critical impurities. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee consistency and compliance with your technical requirements.

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) after opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, oxidizing agents, and water.
