Description

Dichloromethoxymethylsilane is a versatile organosilicon compound, also known as Methoxymethyldichlorosilane, serving as a key intermediate in the synthesis of functional silanes and silicone polymers. Its value lies in its bifunctional reactivity, where the chlorosilane groups enable hydrolysis and condensation reactions, while the methoxy group offers alternative grafting pathways, making it essential for creating tailored surface modifications and cross-linked networks. This chemical is primarily needed by manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for applications ranging from protective coatings to the production of specialized silicone resins.

Application

• Silicone Resin & Polymer Intermediate: A crucial monomer for synthesizing methoxy-functional silicone resins used in heat-resistant coatings and release agents.
• Surface Modification & Coupling Agent: Used to treat inorganic surfaces like glass or silica, improving adhesion and compatibility in composite materials.
• Pharmaceutical Intermediate: Serves as a building block in the synthesis of active pharmaceutical ingredients (APIs) and other silicon-containing drug molecules.
• Agrochemical Synthesis: Employed in the production of silicon-based agrochemicals and plant growth regulators.
• Water Repellent Formulations: A key component in creating water-repellent treatments for textiles, construction materials, and stone.
• Adhesive & Sealant Cross-linking: Acts as a cross-linker or modifier in silicone-based adhesive and sealant formulations to enhance properties.
• Laboratory Reagent: Used in research and development for organosilicon chemistry and material science.
• Precursor for Silane Coupling Agents: A starting material for manufacturing other functional silane coupling agents with specific organic groups.

Quality Control

Our Dichloromethoxymethylsilane is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment, ensuring full traceability and compliance with customer specifications and industry best practices.

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) to prevent moisture absorption and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, acids, and oxidizing agents.
