Description

Dimethylphenylsilane is a versatile organosilicon compound with the CAS number 766-77-8, serving as a key intermediate in advanced material synthesis. Its value lies in its reactivity as a hydrosilane, enabling precise functionalization and cross-linking in polymer and surface chemistry. This product is essential for manufacturers in the silicone, pharmaceutical, and electronics industries seeking to develop high-performance materials.

Application

• Silicone Resin & Polymer Modification: Acts as a reactive intermediate or cross-linking agent in the production of specialty silicone polymers and resins.
• Surface Treatment & Coupling Agent: Used to modify inorganic surfaces (e.g., glass, silica) to impart hydrophobic or specific functional properties.
• Pharmaceutical Intermediate: Serves as a building block in the synthesis of silicon-containing active pharmaceutical ingredients (APIs) and other fine chemicals.
• Semiconductor & Electronics: Employed in the deposition of silicon-containing thin films and as a precursor in chemical vapor deposition (CVD) processes.
• Adhesive & Sealant Formulation: Functions as an adhesion promoter and cross-linker in high-performance silicone-based adhesives and sealants.
• Organic Synthesis: Utilized as a reducing agent (hydrosilylation) or protecting group reagent in complex organic synthesis.

Quality Control

Our Dimethylphenylsilane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 flames.
