Description

Bis(11-Azidoundecyl) Disulfide is a specialized bifunctional organic compound containing both azide and disulfide functional groups. This unique structure makes it a valuable cross-linking agent and click chemistry reagent for advanced material synthesis. It is primarily sought by researchers and manufacturers in the polymer, bioconjugation, and surface modification sectors who require precise molecular control and robust covalent bonding capabilities.

Application

• Polymer Cross-linking Agent: Used to create stable, covalently cross-linked polymer networks, enhancing the mechanical strength and thermal stability of materials like hydrogels and elastomers.
• Surface Functionalization: Enables the grafting of functional molecules onto surfaces (e.g., gold, silica) via disulfide bonding or azide-alkyne cycloaddition for biosensors and advanced coatings.
• Bioconjugation Linker: Facilitates the site-specific attachment of biomolecules (e.g., peptides, antibodies) to carriers or other molecules in drug delivery and diagnostic applications.
• Click Chemistry Reagent: Serves as a key intermediate in Huisgen 1,3-dipolar cycloaddition reactions for the efficient and modular synthesis of complex molecular architectures.
• Material Science Research: Employed in the development of novel self-healing materials, responsive gels, and smart composites due to its reversible disulfide linkage.
• Adhesive Formulation: Acts as a coupling agent to improve adhesion between dissimilar materials in high-performance industrial adhesives and sealants.
