Description

4-Hexenylmethyl Dichlorosilane is a versatile organosilicon compound characterized by its reactive dichlorosilane group and terminal alkene functionality. This dual reactivity makes it a valuable intermediate for synthesizing functional silanes and modifying polymer backbones. It is primarily utilized by manufacturers in the silicone, polymer, and specialty chemical industries for applications requiring tailored surface properties or cross-linking capabilities.

Application

• Silicone Cross-Linking Agent: Used as a reactive intermediate in the production of cross-linked silicone resins and elastomers.
• Surface Modification Reagent: Imparts hydrophobic or specific functional groups to inorganic surfaces like silica, glass, or metals.
• Polymer Functionalization: Serves as a comonomer or grafting agent to introduce silane functionality into organic polymer chains.
• Adhesive & Sealant Formulations: Acts as an adhesion promoter and moisture-cure component in high-performance formulations.
• Specialty Intermediate: Key building block for the synthesis of more complex organosilicon compounds, including silane coupling agents.
• R&D and Pharmaceutical Synthesis: Employed in research laboratories for developing novel materials and pharmaceutical intermediates.

Quality Control

Our 4-Hexenylmethyl Dichlorosilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature: 2-8°C for long-term stability.
