Description

Ethylphenyldichlorosilane is a highly reactive organosilicon compound, specifically a dichlorosilane derivative, serving as a critical building block in advanced material synthesis. Its core value lies in its ability to introduce both ethylphenylsilane and reactive chlorosilane functionalities into polymers and surfaces, enabling precise control over material properties. This chemical is essential for manufacturers and R&D teams in the silicone polymer, specialty coatings, and surface modification sectors who require high-purity intermediates for creating tailored organosilicon architectures.

Application

• Silicone Resin & Polymer Synthesis: A key monomer for introducing phenyl and ethyl groups into silicone backbones, enhancing thermal stability, refractive index, and flexibility of the resulting polymers.
• Surface Modification & Coupling Agent Precursor: Used to synthesize silane coupling agents for improving adhesion between organic polymers and inorganic substrates like glass, metals, or minerals.
• Hydrophobic Coating Formulations: Acts as a reactive intermediate in the production of water-repellent and release coatings for textiles, paper, and construction materials.
• Pharmaceutical & Agro-chemical Intermediates: Serves as a versatile synthon in the synthesis of more complex organosilicon molecules for specialized applications.
• Electronic Materials: Employed in the fabrication of silicone-based encapsulants, dielectrics, and protective layers for semiconductor devices.
• Research & Development: A valuable reagent in academic and industrial labs for exploring new organosilicon chemistry and material science applications.

Quality Control

Our Ethylphenyldichlorosilane is produced under stringent process controls to ensure batch-to-batch consistency and high chemical purity. Every lot undergoes rigorous analytical testing, including gas chromatography (GC) for assay and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and moisture-sensitive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) and handle in a controlled environment to prevent hydrolysis. Recommended storage temperature: 2-8°C for extended stability.
