Description

11-Azidoundecyltrimethoxysilane, 95% is a specialized bifunctional organosilane coupling agent featuring a reactive azide group and a hydrolyzable trimethoxysilane group. This unique structure makes it a critical intermediate for surface modification and covalent attachment strategies in advanced materials science. It is essential for researchers and manufacturers in the fields of polymer chemistry, nanotechnology, and bioconjugation who require precise functionalization of inorganic surfaces like glass, silica, and metals with organic molecules or biomolecules.

Application

• Surface Modification Agent: For covalently attaching organic layers, polymers, or biomolecules to silicon, glass, silica, and metal oxide surfaces via "click chemistry" or other azide-based reactions.
• Polymer Functionalization: As a monomer or crosslinker to introduce azide functionalities into polymer backbones for subsequent modification or network formation.
• Nanomaterial Synthesis: For functionalizing nanoparticles (e.g., silica, quantum dots) to improve dispersion in organic matrices or enable specific bio-targeting.
• Bioconjugation Linker: In the development of biosensors, diagnostic assays, and drug delivery systems, where the azide group enables stable linkage to alkyne-modified biomolecules.
• Adhesion Promoter: In specialty coatings, sealants, and composite materials to enhance the bond between organic polymers and inorganic substrates.
• Research & Development: A key reagent in academic and industrial R&D for exploring new materials, self-assembled monolayers (SAMs), and hybrid organic-inorganic systems.

Quality Control

Our 11-Azidoundecyltrimethoxysilane, 95% undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Each lot is characterized using advanced analytical techniques to confirm identity, purity, and functional integrity. Certificates of Analysis (COA) with detailed specifications are available upon request to support your quality assurance protocols.

Storage

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