Description

Dichlorodiethylsilane is a highly reactive organosilicon compound, primarily used as a versatile intermediate in organosilicon chemistry. Its value lies in its ability to introduce diethylsilyl groups into molecules, serving as a key building block for more complex silanes, silicones, and surface-modifying agents. This product is essential for manufacturers and R&D teams in the pharmaceutical, agrochemical, and advanced materials sectors seeking to develop novel silicon-containing compounds.

Application

• Silicone Intermediate: A crucial precursor in the synthesis of various silicone polymers, resins, and elastomers.
• Surface Modification Agent: Used to functionalize inorganic surfaces (e.g., silica, glass) with hydrophobic diethylsilyl groups.
• Pharmaceutical & Agrochemical Synthesis: Serves as a key intermediate for introducing silicon into active pharmaceutical ingredients (APIs) and agrochemicals to modify their properties.
• Coupling Agent: Acts as a linker or cross-linking agent in hybrid organic-inorganic materials and composite systems.
• Laboratory Reagent: Employed in research and development for the preparation of novel organosilicon compounds and catalysts.
• Water Repellent Treatments: Used in formulations to impart water-resistant properties to textiles, stone, and other materials.

Quality Control

Our Dichlorodiethylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC (Gas Chromatography) for purity and identity verification, to ensure it meets high-purity standards suitable for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C (refrigerated) for extended stability.
