Description

Bis(Dimethylamino)Methylchlorosilane CAS NO 10339-02-3 is a highly reactive organosilicon compound that serves as a versatile intermediate in advanced chemical synthesis. Its value lies in its dual functionality, featuring both a chlorosilane and dimethylamino groups, which makes it a critical precursor for introducing silyl-protecting groups and modifying surfaces. This chemical is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require precise molecular building blocks for creating complex, high-value products.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing silicon-based protecting groups during complex multi-step syntheses.
• Surface Modification Agent: Employed to functionalize silica, glass, and other inorganic surfaces, altering their hydrophobicity, adhesion, and reactivity for advanced materials.
• Polymer & Resin Chemistry: Acts as a cross-linking agent or a monomer modifier in the production of specialty silicones and high-performance polymers.
• Agrochemical Synthesis: Serves as a key intermediate in the development of novel pesticides and herbicides that require silicon-containing moieties.
• Chemical Vapor Deposition (CVD) Precursor: Utilized in the semiconductor industry for depositing silicon nitride or silicon carbonitride thin films on wafers.
• Laboratory Reagent: A valuable reagent in organic synthesis for silylation reactions, facilitating the protection of alcohols, amines, and other functional groups.

Quality Control

Our Bis(Dimethylamino)Methylchlorosilane 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 purity, identity, and impurity profiles is provided with each shipment to guarantee compliance with your specific research or production requirements.

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 moisture-sensitive and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (argon or nitrogen) and separated from strong oxidizers and acids.
