Description

1,3-Bis(Trichlorosilyl)Propane is a specialized organosilicon compound featuring two reactive trichlorosilyl groups. This structure makes it a valuable high-purity precursor for synthesizing advanced silicone polymers and inorganic-organic hybrid materials. It is essential for manufacturers and R&D facilities in the semiconductor, specialty polymer, and advanced materials sectors requiring precise molecular building blocks.

Application

• Precursor for Silicone Polymers: Serves as a key monomer or cross-linking agent in the synthesis of novel polysiloxanes and silicone resins with tailored properties.
• Semiconductor Manufacturing: Used in chemical vapor deposition (CVD) or atomic layer deposition (ALD) processes to deposit silicon carbide (SiC) or silicon-containing thin films.
• Advanced Ceramics & Composites: Acts as a molecular precursor for silicon carbide fibers and ceramic matrix composites via polymer-derived ceramic routes.
• Surface Modification & Coupling Agent: Functionalizes inorganic surfaces (e.g., silica, metals) to improve adhesion and compatibility in composite materials.
• Hybrid Organic-Inorganic Materials: A building block for sol-gel chemistry to create optically clear, high-performance coatings and glasses.
• Pharmaceutical & Chemical Intermediates: Employed in the synthesis of complex organosilicon molecules for research and specialty chemical applications.

Quality Control

Our 1,3-Bis(Trichlorosilyl)Propane is manufactured under stringent process controls to ensure high purity and batch-to-batch consistency. Each lot undergoes comprehensive analysis, including assay by GC or titration and impurity profiling. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its highly volatile and hygroscopic nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature: 2-8°C for extended stability.
