Description

2-Cyanoethyltrichlorosilane is a versatile organosilicon compound that serves as a critical intermediate in advanced material synthesis. Its unique structure, featuring both a reactive trichlorosilyl group and a cyanoethyl moiety, makes it a valuable building block for introducing functional groups onto surfaces and into polymer chains. This chemical is essential for manufacturers and R&D laboratories in the electronics, specialty polymer, and surface treatment industries seeking to create materials with tailored adhesion, release, or dielectric properties.

Application

• Silane Coupling Agent: Used to modify inorganic surfaces like glass, silica, and metals to improve adhesion with organic polymers, resins, and coatings.
• Polymer Synthesis: Acts as a functional monomer or cross-linking agent in the production of specialty silicones, polyimides, and other high-performance polymers.
• Electronics & Semiconductor Manufacturing: Employed in the surface passivation of wafers and as a precursor for low-k dielectric materials and protective layers.
• Chromatography Stationary Phases: Used to derivatize silica gel for HPLC columns, creating phases with specific polarities and separation capabilities.
• Adhesive & Sealant Formulations: Enhances the bonding strength and environmental resistance of adhesives, particularly on difficult-to-bond substrates.
• Hydrophobic Coatings: Serves as a key ingredient in formulating water-repellent and anti-corrosive coatings for textiles, optics, and construction materials.

Quality Control

Our 2-Cyanoethyltrichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC and FTIR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize hydrolysis and volatility. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening and handled in a controlled, moisture-free environment.
