Description

11-Azidoundecyltriethoxysilane, 95% is a specialized bifunctional organosilane coupling agent featuring a long hydrocarbon chain terminated with an azide group and a triethoxysilyl group. This unique structure is critical for creating robust covalent linkages between inorganic surfaces and organic polymers or biomolecules. It is essential for researchers and manufacturers in advanced materials science who require precise surface functionalization to enhance adhesion, introduce click chemistry handles, or create hybrid materials. The product is supplied at a purity of 95% to ensure consistent performance in demanding applications.

Application

• Surface Modification of Inorganic Materials: Used to functionalize silica, glass, metals, and other oxide surfaces, introducing reactive azide groups for subsequent "click" chemistry reactions.
• Polymer & Composite Enhancement: Acts as a coupling agent in polymer composites (e.g., silica-filled rubbers, fiber-reinforced plastics) to improve interfacial adhesion and mechanical properties.
• Bioconjugation & Biosensor Fabrication: Enables the covalent immobilization of biomolecules (proteins, oligonucleotides) onto sensor chips or nanoparticle surfaces via azide-alkyne cycloaddition.
• Hydrophobic Coating Precursor: Serves as a key ingredient in formulating durable water-repellent and anti-corrosion coatings for various substrates.
• Nanomaterial Functionalization: Critical for modifying carbon nanotubes, graphene oxide, and other nanomaterials to improve dispersion and introduce specific chemical functionality.
• Adhesive & Sealant Formulations: Incorporated to enhance the bonding strength and environmental resistance of silicone-based adhesives and sealants.

Quality Control

Our 11-Azidoundecyltriethoxysilane, 95% is manufactured under strict quality control protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment. We adhere to industry best practices and can support compliance requirements for research and industrial applications.

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, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
