Description

Chlorodimethyl(3-Phenylpropyl)Silane CAS NO 17146-09-7 is a versatile organosilicon compound featuring a reactive chlorosilane group and a phenylpropyl substituent. This structure makes it a valuable intermediate for introducing hydrophobic and organophilic properties into advanced materials. It is primarily sought after by manufacturers in the silicone polymer and specialty chemical industries for its role as a key building block. Its utility extends to applications requiring tailored surface characteristics and specific organic-inorganic hybrid functionalities.

Application

• Silicone Resin & Polymer Modification: Acts as a functional monomer or chain terminator to incorporate phenyl groups, enhancing thermal stability, refractive index, and compatibility with organic matrices.
• Surface Treatment Agent: Used to modify the surface of silica, glass, or metals, imparting hydrophobicity and improving adhesion in composite materials and coatings.
• Pharmaceutical & Agrochemical Intermediates: Serves as a key synthon in the synthesis of more complex organosilicon molecules for active ingredient development.
• Adhesive & Sealant Formulations: Incorporated to adjust rheological properties, cure characteristics, and environmental resistance of silicone-based adhesives and sealants.
• Release Coatings & Molding Agents: Utilized in the production of silicone release liners and as a component in mold-making materials for its non-stick properties.
• Research & Development: Employed in academic and industrial R&D for exploring new organosilicon chemistry, dendrimers, and novel hybrid materials.

Quality Control

Our Chlorodimethyl(3-Phenylpropyl)Silane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong acids and organic solvents.
