Description

1,8-Bis(Chlorodimethylsilyl)Octane is a bifunctional organosilicon compound featuring reactive chlorosilane groups at both ends of an octane bridge. This structure makes it a valuable key intermediate for synthesizing linear silicone polymers and modifying organic materials with silicon-based functionalities. It is primarily used by manufacturers in the silicone elastomer, adhesive, and specialty chemical industries to create custom siloxane chains and enhance material properties.

Application

• Silicone Polymer Synthesis: Serves as a chain extender or cross-linker in the production of linear and cross-linked polydimethylsiloxanes (PDMS).
• Surface Modification Agent: Used to impart hydrophobic or release properties to surfaces of glass, minerals, or polymers.
• Adhesive & Sealant Formulations: Acts as a coupling agent or moisture-cure component in high-performance silicone-based adhesives and sealants.
• Hybrid Material Production: A precursor for creating organic-inorganic hybrid (OIH) materials and silsesquioxanes.
• Pharmaceutical & Cosmetic Intermediates: Employed in the synthesis of specialized silicone derivatives for controlled release or sensory enhancement.
• Research & Development: Utilized in academic and industrial R&D for exploring new silicone chemistry and material science applications.

Quality Control

Our 1,8-Bis(Chlorodimethylsilyl)Octane is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality systems are designed to meet the stringent requirements of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity. Keep away from moisture, strong bases, and oxidizing agents.
