Description

(10-Bromodecyl)Triethoxysilane is a bifunctional organosilane coupling agent featuring a long-chain bromoalkyl group and hydrolyzable ethoxysilyl groups. This unique structure makes it a critical intermediate for introducing reactive bromine functionality onto inorganic surfaces or within polymer matrices. It is essential for manufacturers and R&D teams in advanced materials science seeking to create covalently bonded, functional interfaces. Key target industries include specialty polymers, surface modification, and the development of high-performance composites and adhesives.

Application

• Surface Modification Agent: Used to functionalize silica, glass, metals, and other inorganic surfaces with a reactive bromine terminus for subsequent grafting or click chemistry reactions.
• Polymer Synthesis & Modification: Serves as a chain transfer agent, initiator, or comonomer in controlled radical polymerizations (e.g., ATRP) to synthesize block copolymers or introduce bromine handles into polymer backbones.
• Adhesive & Sealant Formulations: Enhances adhesion between organic polymers and inorganic substrates (e.g., glass, metals, minerals) in high-performance sealants, coatings, and adhesives.
• Composite Materials: Improves the dispersion and interfacial bonding of fillers (like glass fibers or minerals) within plastic and rubber composites, leading to superior mechanical properties.
• Chromatography & Separation Media: Functionalizes stationary phases (e.g., silica gel) for HPLC or solid-phase extraction to create materials with specific separation capabilities.
• Nanomaterial Functionalization: A key reagent for modifying nanoparticles (silica, quantum dots) to impart specific chemical reactivity or compatibility with host systems.

Quality Control

Our (10-Bromodecyl)Triethoxysilane is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation.
