Chloromethyl(methyl)dimethoxysilane, identified by the CAS number 2212-11-5, is a chemical compound that holds significant importance in various industrial applications, particularly in materials science and chemical synthesis. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of this versatile organosilane, and understanding its chemical properties is key to unlocking its full potential.

Chemically, Chloromethyl(methyl)dimethoxysilane is characterized by its molecular formula C₄H₁₁ClO₂Si and a molecular weight of approximately 154.67 g/mol. It typically appears as a colorless, transparent liquid. Its structure features a central silicon atom bonded to a methyl group, a chloromethyl group (-CH₂Cl), and two methoxy groups (-OCH₃). This unique combination of functional groups dictates its reactivity and utility.

The methoxy groups are susceptible to hydrolysis, especially in the presence of moisture or acidic/basic catalysts. This reaction forms silanol groups (Si-OH), which can then undergo condensation reactions to form siloxane bonds (Si-O-Si). This property makes Chloromethyl(methyl)dimethoxysilane an effective component in sol-gel processes and for forming cross-linked siloxane networks, which are crucial for many silicone-based materials.

The chloromethyl group is another highly reactive site. It can undergo nucleophilic substitution reactions, allowing the molecule to be grafted onto various organic substrates or to react with nucleophilic species like amines, thiols, or alcohols. This reactivity is fundamental to its function as a coupling agent, enabling it to form strong covalent bonds between organic and inorganic materials. It also serves as a reactive handle for further chemical modifications, making it a valuable intermediate in organic synthesis.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that the Chloromethyl(methyl)dimethoxysilane supplied meets stringent purity standards. Understanding these chemical properties—its reactivity towards hydrolysis, its potential for condensation, and the versatility of its chloromethyl group—is essential for researchers and manufacturers aiming to optimize its use in their processes. Whether for improving adhesion, synthesizing new materials, or acting as a surface modifier, the chemical characteristics of this silane are key to its broad applicability.
