Description

(3-Phenylpropyl)Methyldichlorosilane is a versatile organosilicon intermediate featuring a reactive dichlorosilane group and a phenylpropyl moiety. This compound is valued for its ability to introduce both hydrophobic and organofunctional properties into silicone polymers and hybrid materials. It is primarily sought by manufacturers in the silicone, specialty polymer, and advanced materials sectors for applications requiring tailored surface characteristics and cross-linking capabilities.

Application

• Silicone Polymer Modification: Acts as a key monomer or cross-linking agent in the synthesis of phenyl-containing silicone oils, resins, and elastomers, enhancing thermal stability and refractive index.
• Surface Treatment & Coupling Agent: Used to functionalize inorganic surfaces like silica, glass, or metals, improving adhesion between organic polymers and inorganic substrates in composite materials.
• Intermediate for Silane Coupling Agents: Serves as a precursor for synthesizing more complex alkoxy or functional silanes used in adhesives, sealants, and coatings.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of silicon-containing bioactive molecules and active ingredients.
• Hydrophobic Coatings: Imparts water-repellent and release properties to surfaces in textile, paper, and construction material treatments.
• Research & Development: Utilized in academic and industrial R&D for developing novel organosilicon compounds and hybrid organic-inorganic materials.

Quality Control

Our (3-Phenylpropyl)Methyldichlorosilane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including gas chromatography (GC) and spectroscopic methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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 away from heat and ignition sources. Due to its moisture-sensitive and highly volatile nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity. Recommended storage temperature: 2-8°C.
