Description

(N,n-Dimethylamino)Dimethylchlorosilane is a highly reactive organosilicon compound that serves as a crucial intermediate in organosilicon chemistry. Its value lies in its dual functionality, featuring both a reactive chlorosilane group and a dimethylamino group, making it an essential building block for introducing silicon-containing moieties into target molecules. This chemical is primarily needed by manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for applications such as surface modification, polymer synthesis, and as a precursor for more complex silanes.

Application

• Silylating Agent: Used to introduce the dimethyl(dimethylamino)silyl group into organic molecules, protecting hydroxyl groups or modifying reactivity in synthetic chemistry.
• Surface Modification: Acts as a coupling agent or primer for glass, silica, metals, and other inorganic surfaces to improve adhesion and compatibility with organic polymers.
• Polymer & Resin Synthesis: Serves as a monomer or cross-linking agent in the production of silicone resins, elastomers, and specialty polymers.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems that require organosilicon components.
• Agrochemical Synthesis: Used in the manufacture of silicon-containing pesticides, herbicides, and plant growth regulators.
• Adhesive & Sealant Formulations: Functions as an adhesion promoter and moisture scavenger in high-performance silicone-based adhesives and sealants.
• Nanomaterial Functionalization: Applied to modify nanoparticles (e.g., silica, quantum dots) to tailor their surface properties for specific applications.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. Each batch is analyzed to confirm identity, purity, and absence of critical impurities. Certificates of Analysis (COA) detailing the results are available upon request. We adhere to a strict quality management system to guarantee batch-to-batch consistency and reliability for your industrial processes.

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 highly volatile and hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as water, alcohols, strong bases, and oxidizing agents.
