Description

Methylphenylsilane is a versatile organosilicon compound characterized by its silicon-hydrogen (Si-H) bond and phenyl group. This functional group combination makes it a valuable intermediate in the synthesis of advanced silicone polymers, resins, and specialty materials. It is particularly sought after by manufacturers in the electronics, coatings, and pharmaceutical industries for its role in creating high-performance, heat-resistant, and optically clear products. Our supply of Methylphenylsilane CAS NO 766-08-5 ensures consistent quality and reliable availability for your critical production processes.

Application

• Silicone Polymer Synthesis: A key monomer or cross-linking agent for producing phenyl-modified silicone oils, resins, and elastomers with enhanced thermal stability and optical properties.
• Electronics & Semiconductor Manufacturing: Used as a precursor in chemical vapor deposition (CVD) for depositing silicon carbide (SiC) or silicon-containing thin films on substrates.
• Surface Modification & Adhesion Promotion: Serves as a coupling agent or surface treatment to improve the adhesion of coatings, inks, and adhesives to various substrates.
• Pharmaceutical Intermediates: Employed in the synthesis of organosilicon-based active pharmaceutical ingredients (APIs) and drug delivery systems.
• Specialty Chemicals & Catalysis: Acts as a reducing agent or reactive intermediate in organic synthesis and homogeneous catalysis.
• Advanced Material Research: Utilized in R&D for developing novel hybrid organic-inorganic materials, such as sol-gel glasses and nanocomposites.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers and bases.
