Description

11-Azido-1-Undecanethiol is a specialized bifunctional organic compound featuring both a terminal thiol (-SH) and an azido (-N3) group separated by an undecyl chain. This unique structure makes it a critical heterobifunctional linker for advanced surface chemistry and bioconjugation, enabling the controlled, sequential attachment of diverse molecules. It is essential for researchers and manufacturers in nanotechnology, biosensor development, and materials science who require precise, covalent surface functionalization under mild conditions.

Application

• Self-Assembled Monolayer (SAM) Formation: Used to create functionalized surfaces on gold, silver, and other metals for sensor platforms and electrode modification.
• Click Chemistry Conjugation: The azide group participates in copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient bioconjugation of proteins, peptides, or polymers.
• Nanoparticle Functionalization: Acts as a linker to tether targeting ligands, dyes, or drug molecules onto metallic or quantum dot nanoparticles.
• Polymer and Surface Modification: Introduces reactive azide handles onto polymer backbones or material surfaces for subsequent click chemistry reactions.
• Biointerface Engineering: Facilitates the creation of well-defined, mixed monolayers for studying cell-surface interactions and developing diagnostic chips.
• Microarray and Chip Fabrication: Enables the patterned immobilization of biomolecules on sensor surfaces for high-throughput screening.
