Description

Tetrakis(Trichlorosilylethyl)Silane is a highly functionalized organosilicon compound characterized by its four reactive trichlorosilyl arms. This unique molecular architecture makes it a critical precursor and cross-linking agent in advanced material synthesis, offering exceptional control over polymer network formation and surface modification. It is primarily utilized by R&D chemists and material scientists in the semiconductor, specialty polymer, and nanotechnology sectors for creating high-performance silicones, hybrid organic-inorganic materials, and tailored surface coatings.

Application

• Precursor for Hyperbranched and Dendritic Polymers: Serves as a core molecule for synthesizing complex, three-dimensional silicon-based polymer architectures with controlled branching.
• Surface Modification and Coupling Agent: Used to functionalize inorganic surfaces (e.g., silica, metals) with reactive chlorosilyl groups to enhance adhesion and compatibility with organic matrices.
• Synthesis of Specialty Silicone Resins and Elastomers: Acts as a cross-linker to produce high-temperature resistant and mechanically robust silicone materials with tailored properties.
• Advanced Semiconductor Materials: Employed in the research and development of low-k dielectric materials and other silicon-based thin film precursors for microelectronics.
• Hybrid Organic-Inorganic Materials (Ormosils): A key building block for sol-gel chemistry, creating materials that combine the properties of glass and polymers for optical and coating applications.
• Chemical Intermediate for Further Functionalization: The reactive Si-Cl bonds can be substituted with various organic groups to create a library of novel silylating agents.

Quality Control

Our Tetrakis(Trichlorosilylethyl)Silane is produced and handled under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR for identity confirmation and purity assessment, to ensure consistency and compliance with research-grade specifications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and R&D documentation.

Storage

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