Description

M,p-Ethylphenethyldimethylchlorosilane, Tech-95 is a specialized organosilicon reagent, a chlorosilane derivative designed for high-performance surface modification and chemical synthesis. This compound is valued for its ability to introduce hydrophobic and organofunctional groups onto substrates, significantly altering surface properties for advanced material applications. It is essential for R&D and production in the silicone polymer, advanced coatings, and specialty chemical industries where precise molecular grafting is required.

Application

• Surface Modification Agent: Used as a coupling agent or primer to functionalize glass, silica, metals, and other inorganic surfaces for improved adhesion and hydrophobicity.
• Intermediate for Silicone Synthesis: Serves as a key building block in the production of custom polysiloxanes, silicone resins, and silane-modified polymers.
• Pharmaceutical & Agrochemistry Intermediates: Employed in the synthesis of complex molecules where the introduction of a phenethyl-dimethylsilyl group is required.
• Chromatography Stationary Phases: Utilized to derivatize silica gel for the preparation of specialized HPLC columns with unique selectivity.
• Adhesive & Sealant Formulations: Acts as an adhesion promoter and crosslinking agent in high-performance silicone-based adhesives and sealants.
• Nanomaterial Functionalization: Critical for surface treatment of nanoparticles (e.g., silica, quantum dots) to enhance dispersion in organic matrices and tailor interfacial properties.

Quality Control

Our M,p-Ethylphenethyldimethylchlorosilane, Tech-95 is manufactured under strict process controls to ensure batch-to-batch consistency and reliability. The product undergoes rigorous quality testing, including assay by GC or titration and impurity profiling, to meet the declared 95% minimum purity specification. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and relevant physical properties 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 at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases and incompatible materials.
