Description

Diphenylchlorosilane is a versatile organosilicon compound widely used as a key intermediate in the synthesis of advanced silicone polymers and functional silanes. Its value lies in its reactive chlorosilane group, which enables the introduction of diphenylsiloxy units into molecular structures, enhancing thermal stability and modifying physical properties. This product is essential for manufacturers in the silicone resins, adhesives, and specialty chemical sectors, as well as for research institutions developing novel organosilicon materials.

Application

• Silicone Resin & Polymer Synthesis: A fundamental building block for creating heat-resistant silicone resins, elastomers, and high-performance polymers.
• Surface Modification & Coupling Agents: Used to produce silane coupling agents that improve adhesion between organic polymers and inorganic surfaces like glass or metals.
• Pharmaceutical & Agro-Intermediate: Serves as a precursor in the synthesis of more complex organosilicon compounds used in active ingredient development.
• Electronics & Semiconductor Industry: Employed in the production of dielectric materials, insulating coatings, and precursors for silicon carbide (SiC) or silicon nitride (Si3N4) thin films via Chemical Vapor Deposition (CVD).
• Hydrophobic Coatings: A key intermediate for formulating water-repellent surface treatments for textiles, construction materials, and electronics.
• Research & Development: Crucial for academic and industrial R&D in organometallic chemistry and material science for creating novel hybrid materials.

Quality Control

Our Diphenylchlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets precise specifications for purity and reactivity. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing all quality parameters. We adhere to relevant industry standards and can support compliance needs for global markets, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids, bases, and oxidizing agents.
