Description

[(11-Chloroundecyl)Oxy]Trimethylsilane is a specialized organosilicon compound featuring a long alkyl chain terminated with a reactive chloromethyl group and a trimethylsilyl ether. This unique bifunctional structure makes it a valuable intermediate for surface modification and the synthesis of functional materials. It is primarily sought by R&D and production teams in the advanced materials, specialty chemicals, and life sciences sectors for creating tailored silane coupling agents, hydrophobic coatings, and polymer modifiers.

Application

• Silane Coupling Agent Precursor: Serves as a key intermediate for synthesizing novel silane coupling agents with long hydrocarbon tethers for enhanced compatibility with organic polymers.
• Surface Modification: Used to functionalize inorganic surfaces like silica, glass, or metals to impart hydrophobic properties and introduce reactive chloromethyl sites for further chemical grafting.
• Polymer Synthesis & Modification: Acts as a monomer or chain transfer agent in the synthesis of specialty silicones and hybrid organic-inorganic polymers, influencing material properties like flexibility and surface energy.
• Chromatography Media: Employed in the derivatization of stationary phases for HPLC or GC columns to achieve specific separation selectivities based on hydrophobic interactions.
• Nanomaterial Functionalization: Utilized to coat nanoparticles (e.g., silica, quantum dots) to improve dispersion in organic solvents and provide anchor points for subsequent bioconjugation or labeling.
• Adhesive & Sealant Formulations: Incorporated as an additive to enhance the adhesion and moisture resistance of silicone-based adhesives and sealants to various substrates.
