Description

5-Hexenylmethyl Dichlorosilane is a highly reactive organosilicon compound characterized by its dichlorosilane functionality and terminal alkene group. This dual reactivity makes it a versatile intermediate for introducing silicon-containing moieties into polymer backbones and for surface modification applications. It is primarily utilized by manufacturers in the silicone polymer, specialty adhesives, and advanced materials sectors seeking to enhance product performance through custom silane chemistry.

Application

• Key intermediate in the synthesis of custom siloxane polymers and silicone-based elastomers.
• Surface modifying agent for inorganic fillers (e.g., silica, glass) to improve compatibility with organic polymer matrices.
• Crosslinking agent in the production of moisture-curable resins and sealants.
• Precursor for functional silanes, such as alkoxysilanes or aminosilanes, via subsequent chemical transformations.
• Hydrophobic coating formulations for textiles, paper, and construction materials.
• Used in research and development for creating novel hybrid organic-inorganic materials (ORMOSILs).

Quality Control

Our 5-Hexenylmethyl Dichlorosilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each production lot undergoes comprehensive analytical testing. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, store under a dry inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to minimize degradation and volatility. Keep away from moisture, heat, and incompatible materials such as strong bases and oxidizing agents.
