Description

Dichloromethylsilane is a highly reactive organosilicon compound, serving as a fundamental building block in organosilicon chemistry. Its primary value lies in its role as a versatile intermediate for introducing the methylchlorosilane functional group into more complex molecules. This product is essential for manufacturers and R&D facilities in the silicone polymer, pharmaceutical, and advanced materials sectors. Dichloromethylsilane CAS NO 75-54-7 is particularly critical for synthesizing silane coupling agents, silicone resins, and as a precursor for further functionalization.

Application

• Silicone Intermediate: A key monomer and intermediate in the production of various silicone polymers, fluids, and elastomers.
• Silane Coupling Agent Synthesis: Used to manufacture coupling agents that improve adhesion between organic polymers and inorganic surfaces like glass, minerals, and metals.
• Surface Modification: Employed to modify surface properties of silica, glass, and other materials to impart hydrophobicity or specific reactivity.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of certain organosilicon-based active pharmaceutical ingredients (APIs) and reagents.
• Protective Group Chemistry: Utilized in organic synthesis to introduce protecting groups for alcohols and other functional groups.
• Precursor to Other Silanes: Acts as a starting material for the production of other functional chlorosilanes and alkoxysilanes through substitution reactions.

Quality Control

Our Dichloromethylsilane is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling. Certificates of Analysis (COA) detailing all test results are provided with every shipment and are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Store separately from strong bases and oxidizers.
