Description

Di(2-Ethylhexyl)Dichlorosilane is a specialized organosilicon compound characterized by its dichlorosilane functional group and branched 2-ethylhexyl substituents. This structure makes it a valuable intermediate for introducing hydrophobic, bulky alkylsilane groups into target molecules and materials. It is primarily sought after by R&D chemists and process engineers in advanced material science and fine chemical synthesis. The compound's reactivity is leveraged to modify surfaces and create custom silane coupling agents with specific steric and solubility properties.

Application

• Silane Coupling Agent Precursor: Serves as a key intermediate for synthesizing custom silane coupling agents used in composite materials, adhesives, and coatings to improve interfacial bonding between organic polymers and inorganic surfaces.
• Surface Modification: Used to hydrophobically modify silica, glass, and other metal oxide surfaces, imparting water-repellent properties and altering surface energy for specific applications.
• Polymer Functionalization: Employed to introduce bulky, hydrophobic side chains into polymers via hydrosilylation or other reactions, modifying physical properties like glass transition temperature, solubility, and flexibility.
• Pharmaceutical & Agrochemical Intermediates: Acts as a building block in the multi-step synthesis of complex molecules for active ingredients, where the silane group is used for protection, coupling, or to influence bioavailability.
• Specialty Material Synthesis: Utilized in the research and development of novel silicone-based fluids, resins, and elastomers with tailored properties for high-performance applications.

Quality Control

Every batch of Di(2-Ethylhexyl)Dichlorosilane is produced and analyzed under strict quality management protocols. We ensure consistent purity and reactivity through comprehensive analytical testing, including GC, NMR, and titration methods. A Certificate of Analysis (COA) detailing batch-specific results for identity, purity, and key impurities is provided with each shipment, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong acids, and bases. Containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
