Description

(5-Hexenyl)Dimethylchlorosilane is a versatile organosilicon compound featuring a terminal alkene group and a reactive chlorosilane moiety. This dual functionality makes it a valuable intermediate for introducing hydrophobic, cross-linkable, or surface-modifying groups in advanced materials. It is essential for manufacturers and R&D chemists in the silicone polymer, surface treatment, and specialty chemical synthesis sectors seeking to create custom siloxane architectures or functionalized surfaces.

Application

• Silicone Polymer Modification: Serves as a key monomer or chain extender for synthesizing specialty silicone elastomers, resins, and fluids with pendant vinyl groups for subsequent cross-linking or functionalization.
• Surface Coupling Agent: Used to functionalize inorganic surfaces (e.g., silica, glass, metals) by forming stable siloxane bonds, imparting hydrophobic properties or providing an alkene handle for further chemical grafting.
• Organic Synthesis Intermediate: The reactive chlorosilane and alkene groups allow for sequential hydrosilylation and other reactions, enabling the synthesis of complex, tailor-made organosilicon molecules.
• Adhesive & Sealant Formulations: Incorporated as an adhesion promoter or a cross-linking component in high-performance silicone-based adhesive and sealant systems.
• Release Coatings: A precursor for creating silicone release liners with controlled surface energy and release properties for labels and tapes.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of silane-containing active ingredients or prodrugs that leverage silicon's unique biological properties.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong acids, and bases. Containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, and open flame.
