Description

Ethyldichlorosilane is a highly reactive organosilicon compound primarily used as a key building block in silicone chemistry. Its value lies in its ability to introduce ethyl groups and reactive chlorosilane functionalities into polymers and surfaces, enabling the creation of specialized materials. This chemical is essential for manufacturers in the silicone, pharmaceutical, and advanced materials sectors who require precise intermediates for synthesis and surface modification.

Application

• Silicone Intermediate: A fundamental precursor in the production of ethyl-substituted silicone oils, resins, and elastomers.
• Surface Modification Agent: Used to impart hydrophobic properties to glass, silica, and other inorganic surfaces via silanization.
• Pharmaceutical Synthesis: Serves as a versatile reagent for introducing silyl protecting groups in complex organic and drug molecule synthesis.
• Adhesive & Sealant Formulation: Acts as a cross-linking agent and adhesion promoter in high-performance silicone-based formulations.
• Chemical Vapor Deposition (CVD): Employed as a source for depositing silicon-containing thin films in semiconductor and optics manufacturing.
• Laboratory Reagent: Utilized in research and development for organometallic chemistry and material science experiments.

Quality Control

Our Ethyldichlorosilane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting standards for industrial and laboratory use. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. 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 oxidation. Recommended storage temperature is 2-8°C.
