Description

11-Bromoundecyldimethylchlorosilane is a bifunctional organosilane coupling agent featuring a reactive bromoalkyl chain and a chlorosilane head group. This compound is engineered to serve as a critical molecular bridge, enabling the covalent attachment of organic molecules to inorganic surfaces or polymer matrices. It is essential for researchers and manufacturers in advanced materials science, particularly for developing functionalized surfaces, specialized polymers, and high-performance coatings where durable chemical bonding is required.

Application

• Surface Modification Agent: Used to functionalize silica, glass, metals, and other inorganic oxides to alter surface properties such as hydrophobicity, adhesion, or reactivity.
• Polymer Synthesis & Modification: Acts as a monomer or cross-linking agent in the synthesis of silicone copolymers and hybrid organic-inorganic materials.
• Chromatography Stationary Phases: Employed to derivatize silica gel for the preparation of reversed-phase or specialty HPLC columns.
• Nanomaterial Functionalization: Key for grafting onto nanoparticles (e.g., silica, quantum dots) to impart specific chemical functionalities for sensing, catalysis, or drug delivery applications.
• Adhesion Promotion: Enhances the bonding between organic polymers (like epoxies, polyimides) and inorganic substrates in composite materials and electronic encapsulants.
• Intermediate for Further Synthesis: The bromoalkyl group serves as a versatile handle for nucleophilic substitution reactions (e.g., with amines, thiols, azides) to create a wide array of custom silane derivatives.

Quality Control

Our 11-Bromoundecyldimethylchlorosilane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, GC, and titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing specific batch results are provided to guarantee compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its moisture-sensitive (hygroscopic) nature, containers should be kept sealed under an inert atmosphere (argon or nitrogen) when not in use to prevent hydrolysis. Recommended storage temperature: 2-8°C for long-term stability.
