Description

10-Undecenyldimethylchlorosilane is a versatile organosilicon reagent featuring a terminal alkene group and a reactive chlorosilane moiety. This bifunctional structure is critical for its role as a key intermediate in the synthesis of specialized silane coupling agents and functionalized polymers. It is essential for manufacturers and R&D laboratories in the advanced materials, adhesives, and life sciences sectors seeking to modify surface properties or create custom silicone-based architectures.

Application

• Surface Modification Agent: Used to functionalize inorganic surfaces like silica, glass, and metals, imparting hydrophobic properties or providing an alkene-terminated layer for further chemical grafting.
• Silicone Polymer Synthesis: Serves as a reactive monomer or chain extender in the production of specialty silicone polymers, elastomers, and resins with tailored properties.
• Crosslinking Agent: Employed in formulations for adhesives, sealants, and coatings to enhance durability, adhesion, and thermal stability through siloxane bond formation.
• Bioconjugation Linker: The alkene group allows for further functionalization via click chemistry (e.g., thiol-ene), making it useful for creating bio-compatible surfaces or drug delivery systems.
• Chromatography Stationary Phases: Used to derivatize silica gel for HPLC columns, creating phases with specific selectivity for analytical separations.
• Nanomaterial Functionalization: Key for modifying nanoparticles (e.g., quantum dots, carbon nanotubes) to improve dispersion in organic matrices or to attach specific functional groups.

Quality Control

Our 10-Undecenyldimethylchlorosilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C under an inert atmosphere (argon or nitrogen). Due to its highly volatile and hygroscopic nature, containers must be kept tightly sealed and handled under dry conditions to prevent moisture ingress and decomposition.
