Description

n-Decylmethyldichlorosilane is a high-purity organosilicon compound, specifically a long-chain alkylchlorosilane. This chemical is a critical intermediate for introducing hydrophobic decyl groups into silicon-based materials, significantly enhancing their surface properties and compatibility. It is essential for manufacturers in the silicone polymer, advanced material science, and specialty chemical synthesis sectors seeking to develop products with tailored release, water repellency, and organic compatibility.

Application

• Silicone Intermediate: A key monomer for the synthesis of specialty silicone oils, resins, and elastomers with long alkyl side chains.
• Surface Modification Agent: Used to hydrophobically modify the surface of silica, glass, metals, and other inorganic materials to impart water repellency and improve dispersion in organic matrices.
• Coupling Agent: Acts as a molecular bridge to improve adhesion between organic polymers and inorganic fillers or substrates in composite materials.
• Pharmaceutical & Agro-chemical Intermediates: Serves as a building block in the synthesis of more complex organosilicon molecules for specialized applications.
• Release Coating Precursor: Used in formulations for creating non-stick and easy-release coatings on papers, films, and molds.
• Research & Development: Employed in laboratories for developing novel silicone-based materials and studying surface chemistry.

Quality Control

Our n-Decylmethyldichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and moisture-sensitive nature, this material must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Keep away from strong acids, bases, and oxidizing agents. Recommended storage temperature is 2-8°C to maximize shelf-life stability.
