Description

10-(Carbomethoxy)Decyltrichlorosilane is a specialized organosilicon compound that serves as a versatile coupling agent and surface modifier. Its molecular structure, featuring a long alkyl chain terminated by a trichlorosilane group and a methoxycarbonyl moiety, enables it to form stable covalent bonds with inorganic substrates while providing an organic functional handle for further chemical reactions. This product is essential for researchers and manufacturers in advanced materials science who require precise surface engineering to enhance adhesion, compatibility, and performance. Key industries that utilize this silane include specialty coatings, microelectronics, and the development of functionalized nanoparticles and chromatographic media.

Application

• Surface Modification of Inorganic Oxides: Used to functionalize glass, silica, quartz, and metal oxide surfaces (e.g., ITO, TiO2) to impart hydrophobic properties or introduce specific reactive sites.
• Adhesion Promotion in Specialty Coatings: Acts as a primer or additive in polymer composites and protective coatings to improve bonding between organic polymers and inorganic substrates.
• Stationary Phase Derivatization for Chromatography: Employed to synthesize reversed-phase or specialty ligand-bonded silica gel for HPLC and solid-phase extraction applications.
• Nanoparticle Functionalization: Crucial for capping and stabilizing nanoparticles (e.g., silica, quantum dots) to prevent aggregation and enable their dispersion in organic solvents or polymer matrices.
• Microelectronics and Semiconductor Fabrication: Applied in the surface treatment of wafers and components to control interfacial properties, dielectric layers, and in self-assembled monolayer (SAM) formation.
• Intermediate for Further Synthesis: The carbomethoxy group can be hydrolyzed to a carboxylic acid or reduced to an alcohol, making it a valuable building block for synthesizing more complex silane derivatives with tailored functionality.

Quality Control

Our 10-(Carbomethoxy)Decyltrichlorosilane is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure batch-to-batch consistency and high purity. Quality assurance protocols include identity confirmation via spectroscopic methods and quantitative purity assessment. A comprehensive Certificate of Analysis (COA) detailing specific results for purity, identity, and impurity profiles is provided with each shipment. We adhere to stringent in-house standards to meet the critical requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its moisture-sensitive (hygroscopic) nature, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability. Keep away from incompatible materials such as strong bases and fluorides.
