Description

Chloromethylmethyldiisopropoxysilane is a highly reactive organosilicon compound featuring both chloromethyl and diisopropoxy functional groups, enabling versatile silylation and crosslinking reactions. Its unique bifunctional reactivity makes it a critical intermediate for synthesizing specialty silanes, silicone-modified polymers, and surface-functionalized materials with enhanced adhesion, hydrophobicity, or chemical resistance. This compound is essential for R&D and production teams in advanced materials, silicone elastomer manufacturing, semiconductor packaging, and high-performance coatings. Chloromethylmethyldiisopropoxysilane CAS NO 2212-08-0 is widely specified by global industrial formulators requiring precise control over silane coupling efficiency and hydrolytic stability.

Application

• Synthesis of chloromethyl-functionalized silicone resins for heat-resistant coatings and release agents
• Surface modification of silica nanoparticles and glass fibers to improve dispersion and interfacial bonding in composites
• Key precursor in the preparation of aminoalkylsilanes via nucleophilic substitution (e.g., with amines)
• Coupling agent for adhesion promotion between organic polymers (e.g., epoxies, polyurethanes) and inorganic substrates (glass, metals, ceramics)
• Intermediate in the manufacture of photoresist additives and dielectric materials for microelectronics
• Building block for stimuli-responsive smart gels and hydrogels with tunable degradation profiles
• Reagent for controlled grafting of functional polymers onto silicon wafers and MEMS devices
• Enabling component in moisture-curable RTV (room-temperature vulcanizing) silicone sealants with rapid cure kinetics

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches are verified for identity (IR, GC-MS), assay (GC), and purity (HPLC), with strict limits on volatile impurities and residual solvents. Manufacturing adheres to ISO 9001-certified processes, and technical-grade material meets ACS Reagent Grade specifications for critical parameters including water content and acidity.

Storage

Preserve in a tightly closed container, protected from light. Store under inert atmosphere (nitrogen or argon) at 15–25°C in a dry, well-ventilated area. Due to its hygroscopic nature, minimize exposure to ambient moisture during handling. Keep away from strong acid/organic solvent environments and incompatible materials such as fluorides or strong alkalis.
