Description

(4-Cyclooctenyl)Trichlorosilane is a highly reactive organosilicon compound characterized by a cyclooctenyl group attached to a trichlorosilyl moiety. This structure makes it a valuable intermediate for introducing functional silane groups into organic frameworks, enabling surface modification and polymer cross-linking. It is primarily sought by manufacturers in the advanced materials, specialty polymers, and electronics sectors for developing high-performance coatings, adhesives, and silane coupling agents.

Application

• Silane Coupling Agent: Used to modify inorganic surfaces like glass, silica, and metals to improve adhesion with organic polymers in composite materials.
• Polymer Synthesis & Modification: Serves as a key monomer or cross-linking agent in the production of specialty silicones and hybrid organic-inorganic polymers.
• Surface Functionalization: Applied in the development of hydrophobic, oleophobic, or specific chemically active coatings for textiles, filters, and electronic components.
• Adhesive & Sealant Formulations: Enhances the bonding strength and environmental resistance of high-performance adhesives and sealants.
• Pharmaceutical & Agro-chemical Intermediates: Utilized in the synthesis of complex molecules where the silane group acts as a protecting or functional handle.
• Research & Development: Employed in academic and industrial R&D for exploring new materials science applications and catalytic processes.

Quality Control

Our (4-Cyclooctenyl)Trichlorosilane is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay and impurity profiling by GC and NMR, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) and protected from humidity. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, acids, and oxidizing agents.
