Description

1,2-Dichloroethyltrichlorosilane is a highly reactive organosilicon compound characterized by its chloroalkyl and chlorosilyl functional groups. This dual functionality makes it a valuable intermediate for introducing silicon-containing moieties into organic frameworks, enabling the synthesis of specialized silanes and silicone polymers. It is primarily sought by manufacturers in the chemical, pharmaceutical, and advanced materials sectors for applications requiring precise surface modification or the creation of custom siloxane structures.

Application

• Silane Coupling Agent Precursor: Used to synthesize specialized silane coupling agents for enhancing adhesion between organic polymers and inorganic surfaces like glass, minerals, or metals.
• Intermediate for Specialty Silicones: Serves as a key building block in the production of custom silicone resins, fluids, and elastomers with specific chemical resistance or thermal properties.
• Surface Modification Reagent: Employed to chemically modify material surfaces (e.g., silica, nanoparticles) to impart hydrophobic characteristics or create reactive sites for further functionalization.
• Pharmaceutical Intermediate: Acts as a protected or functionalized synthon in the multi-step synthesis of complex drug molecules containing silicon.
• Crosslinking Agent: Utilized in formulations where it can act as a crosslinker for polymers, improving mechanical strength and chemical stability.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new organosilicon chemistry and material science applications.

Quality Control

Our 1,2-Dichloroethyltrichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets precise specifications for purity and reactivity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

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 must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
