Description

Phenyltrichlorosilane CAS NO 98-13-5 is a key organosilicon intermediate characterized by its reactive trichlorosilyl group attached to a phenyl ring. This compound is essential for introducing phenylsilane functionality into polymers and surfaces, enabling the creation of materials with enhanced thermal stability, hydrophobicity, and adhesion properties. It is primarily sought by manufacturers in the silicone resin, coupling agent, and specialty chemical sectors for advanced material synthesis.

Application

• Silicone Resin Precursor: A fundamental building block for manufacturing phenyl-containing silicone resins, which offer superior heat resistance for high-temperature coatings, electrical insulation, and mold release agents.
• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces like glass, silica, and metals, improving the adhesion between organic polymers and inorganic substrates in composite materials.
• Pharmaceutical & Agrochemical Intermediates: Serves as a versatile synthon in the synthesis of more complex organosilicon compounds used in active ingredient development.
• Water Repellent Treatments: Imparts durable hydrophobic properties to construction materials, textiles, and stone, providing protection against moisture and weathering.
• Silicone Rubber Cross-linking Agent: Acts as a cross-linker in the production of certain high-performance silicone elastomers, enhancing their mechanical properties.
• Semiconductor & Electronics Manufacturing: Employed in chemical vapor deposition (CVD) processes to deposit silicon-containing thin films for microelectronics and optical devices.

Quality Control

Our Phenyltrichlorosilane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical tests including gas chromatography (GC) and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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 hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Store separately from strong bases, oxidizers, and water sources.
