Description

11-Cyanoundecyltrichlorosilane is a specialized bifunctional organosilane coupling agent featuring a long alkyl chain terminated by a nitrile group and a reactive trichlorosilyl head. This unique molecular structure enables it to act as a versatile surface modifier and molecular bridge, creating durable covalent bonds between inorganic substrates and organic polymers or coatings. It is essential for manufacturers and R&D teams in advanced materials science seeking to enhance adhesion, dispersion, and interfacial properties. Key industries that utilize this compound include specialty chemicals, nanotechnology, and high-performance composites.

Application

• Surface Modification of Inorganic Materials: Used to functionalize silica, glass, metals, and other oxides to introduce hydrophobic, oleophobic, or specific reactive (cyano) surface properties.
• Coupling Agent in Composite Materials: Improves the interfacial adhesion and stress transfer between inorganic fillers (e.g., glass fibers, minerals) and polymer matrices like epoxies, polyurethanes, and polyamides.
• Nanoparticle Functionalization: A key reagent for capping and stabilizing metal oxide nanoparticles (e.g., TiO2, ZnO) to prevent agglomeration and facilitate their integration into organic systems.
• Chromatography Stationary Phases: Employed to derivatize silica gel for the preparation of specialized HPLC columns with unique selectivity, particularly for polar compounds.
• Adhesion Promotion: Serves as a primer or additive in coatings, sealants, and adhesives to dramatically improve bond strength to difficult substrates like glass and aluminum.
• Intermediate for Further Synthesis: The terminal cyano group can be hydrolyzed to a carboxylic acid or reduced to an amine, enabling the synthesis of a wide range of other functionalized silanes.
• Self-Assembled Monolayers (SAMs): Used to create ordered molecular films on silicon wafers and other surfaces for applications in sensors, microelectronics, and corrosion inhibition.

Quality Control

Every batch of 11-Cyanoundecyltrichlorosilane is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including NMR, FT-IR, and GC/HPLC, to ensure identity, purity, and consistency meet the high standards required for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee full traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong acids and organic solvents. Store separately from bases and oxidizing agents.
