Description

1,1,3,3,5,5-Hexaethoxy-1,3,5-Trisilacyclohexane is a specialized organosilicon compound, specifically a cyclic silane with six ethoxy substituents, known by the CAS number 17955-67-8. This chemical serves as a high-purity precursor for advanced materials, offering controlled reactivity and silicon incorporation. It is essential for manufacturers and R&D facilities in the electronics, specialty polymers, and advanced coatings sectors seeking to develop novel silicon-based materials with specific properties.

Application

• Precursor for Silicon-Containing Polymers: Used in the synthesis of polysilanes, polycarbosilanes, and other silicon-based polymers for high-performance materials.
• Advanced Ceramics and Composites: Acts as a preceramic polymer source for silicon carbide (SiC) or silicon oxycarbide (SiOC) ceramics via pyrolysis.
• Surface Modification and Coupling Agent: Employed to functionalize inorganic surfaces (e.g., silica, metals) with organic groups to improve adhesion and compatibility in composite systems.
• Thin Film Deposition: Serves as a precursor for chemical vapor deposition (CVD) or atomic layer deposition (ALD) processes to create silicon-based thin films for semiconductor and optical applications.
• Synthesis of Dendrimers and Hyperbranched Polymers: Utilized as a core or branching unit due to its cyclic trisilane structure with multiple reactive sites.
• Research & Development: A key intermediate in organometallic and materials chemistry research for developing new catalysts, sensors, and nanostructured materials.

Quality Control

Our 1,1,3,3,5,5-Hexaethoxy-1,3,5-Trisilacyclohexane is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
