Description

Phenyl(3-Chloropropyl)Dichlorosilane is a versatile organosilicon compound characterized by its reactive chlorosilane and chloropropyl functional groups. This dual functionality makes it a valuable intermediate for introducing phenylsilane moieties into more complex molecular architectures. It is primarily sought after by manufacturers in the silicone polymer, specialty chemical, and pharmaceutical sectors for synthesizing advanced materials, surface modifiers, and silane coupling agents.

Application

• Silane Coupling Agent Precursor: Key intermediate for manufacturing coupling agents used to improve adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Silicone Polymer Modification: Used to introduce phenyl and reactive chloropropyl groups into silicone resins and elastomers, enhancing properties such as thermal stability, refractive index, and compatibility with organic materials.
• Surface Functionalization: Employed to modify silica nanoparticles, glass fibers, and other fillers to create hydrophobic or organophilic surfaces for composite materials.
• Pharmaceutical & Agrochemical Intermediates: Serves as a building block in the synthesis of more complex organosilicon molecules with potential biological activity.
• Specialty Coatings and Resins: A reactive monomer for formulating high-performance phenyl-containing silicone coatings, sealants, and release agents.

Quality Control

Our Phenyl(3-Chloropropyl)Dichlorosilane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including Gas Chromatography (GC) and FT-IR spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and specific 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 incompatible materials. Due to its moisture-sensitive (hygroscopic) nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for extended stability.
