Description

1,2-Bis(Chlorodimethylsilyl)Ethane is a versatile organosilicon compound, specifically a bifunctional chlorosilane, that serves as a critical building block in advanced material synthesis. Its core value lies in its ability to act as a cross-linking agent and precursor for silicone polymers and hybrid organic-inorganic materials, offering enhanced thermal stability and tailored mechanical properties. This high-purity intermediate is essential for manufacturers in the silicone elastomer, specialty resin, and surface modification sectors seeking to develop high-performance products.

Application

• Silicone Polymer Cross-Linking Agent: A key monomer for synthesizing cross-linked polysiloxanes and silicone elastomers with improved heat resistance and mechanical strength.
• Precursor for Hybrid Materials: Used in sol-gel processes to create silicon-based organic-inorganic hybrid (OIH) coatings, films, and composites.
• Surface Modification & Coupling Agent: Functionalizes inorganic surfaces (e.g., silica, glass) to improve adhesion and compatibility with organic polymer matrices.
• Intermediate for Specialty Silanes: Serves as a starting material for synthesizing more complex functional silanes used in adhesives, sealants, and release coatings.
• Pharmaceutical & Electronic Material Synthesis: Employed in the research and development of specialized materials for controlled release systems and electronic encapsulants.

Quality Control

Our 1,2-Bis(Chlorodimethylsilyl)Ethane is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable, and all materials are supported by comprehensive analytical documentation. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee compliance with your specific application requirements.

Storage

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