Description

Chloromethylsilane CAS NO 10112-09-1 is a versatile organosilicon compound characterized by its reactive chloromethyl group bonded to a silicon atom. This high reactivity makes it a valuable intermediate for introducing functional groups into siloxane polymers and other silicon-based materials. It is essential for manufacturers in the silicone, pharmaceutical, and specialty chemical industries seeking to create custom-modified polymers, surface coatings, or advanced material precursors.

Application

• Silicone Polymer Modification: Key intermediate for introducing reactive sites into polysiloxane backbones to create custom silicones with tailored properties.
• Surface Treatment Agent: Used to functionalize glass, silica, and other inorganic surfaces to improve adhesion and compatibility with organic matrices.
• Pharmaceutical Intermediate: Serves as a building block in the synthesis of silicon-containing active pharmaceutical ingredients (APIs) and drug delivery agents.
• Crosslinking Agent: Employed in the production of crosslinked silicone resins and elastomers for high-performance sealants and coatings.
• Adhesion Promoter: Enhances the bond between silicone materials and various substrates in composite and laminate manufacturing.
• Specialty Chemical Synthesis: A crucial precursor for synthesizing more complex organosilicon compounds used in research and advanced material development.

Quality Control

Our Chloromethylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications for industrial and research applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, store under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to minimize volatility and degradation. Keep away from moisture, strong bases, and oxidizing agents.
