Description

Dichlorodi-n-Pentylsilane is a versatile organosilicon compound, specifically a dialkyl dichlorosilane, serving as a critical intermediate in the synthesis of functional siloxanes and silicone polymers. Its value lies in providing a reactive chlorosilane backbone with longer alkyl chains, which imparts unique hydrophobic and organic compatibility properties to the final materials. This chemical is essential for manufacturers and R&D teams in the silicone, specialty chemical, and advanced materials sectors seeking to modify surface properties or create tailored polymeric structures.

Application

• Silicone Intermediate: A key precursor for synthesizing pentyl-substituted siloxane oligomers and polymers, used in specialty lubricants, release agents, and damping fluids.
• Surface Modification Agent: Employed to hydrophobize inorganic surfaces like silica, glass, or metals, enhancing water repellency and organic compatibility.
• Coupling Agent: Acts as a linker between organic polymers and inorganic fillers in composite materials, improving dispersion and mechanical properties.
• Pharmaceutical & Agrochemical Intermediates: Used in the synthesis of more complex organosilicon molecules for active ingredient development or formulation aids.
• Research & Development: Serves as a building block in academic and industrial labs for exploring new silicone-based materials, coatings, and elastomers.
• Waterproofing Additives: Incorporated into formulations for textiles, construction materials, and electronics to provide durable water-resistant coatings.

Quality Control

Our Dichlorodi-n-Pentylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment. We adhere to relevant industry standards and can support compliance documentation as required.

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) to maintain stability and prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents. Recommended storage temperature: 2°C to 8°C (refrigerated) for long-term stability.
