Description

8-Bromooctyltrichlorosilane is a bifunctional organosilicon compound featuring a reactive bromoalkyl chain and a hydrolyzable trichlorosilyl group. This unique structure makes it a versatile coupling agent and surface modifier, enabling the covalent attachment of organic molecules to inorganic substrates. It is primarily used by researchers and manufacturers in the semiconductor, nanotechnology, and advanced materials sectors for creating self-assembled monolayers (SAMs) and functionalized surfaces.

Application

• Surface Functionalization: Key reagent for creating self-assembled monolayers (SAMs) on silicon, glass, and metal oxide surfaces.
• Nanotechnology & Microfabrication: Used as a molecular anchor in the production of biosensors, microfluidic devices, and lab-on-a-chip systems.
• Polymer & Composite Modification: Acts as a coupling agent to improve the adhesion between inorganic fillers and organic polymer matrices.
• Chromatography Media: Employed to derivatize silica gel for the preparation of specialized stationary phases in HPLC and affinity chromatography.
• Organic Synthesis Intermediate: The bromine terminus serves as a handle for further chemical transformations via nucleophilic substitution or metal-catalyzed cross-coupling reactions.
• Adhesion Promotion: Enhances the bonding of coatings, inks, and adhesives to difficult-to-bond substrates like metals and ceramics.

Quality Control

Our 8-Bromooctyltrichlorosilane is produced under stringent conditions to ensure high purity and batch-to-batch consistency. Quality is verified through comprehensive analytical techniques including GC, NMR, and FTIR spectroscopy. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, identity, and relevant physical properties.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (argon or nitrogen). Due to its moisture-sensitive and corrosive nature, keep the container tightly sealed and handle in a controlled, dry environment.
