Description

11-Azido-Undecanoic Acid is a bifunctional organic compound featuring a terminal azide group and a carboxylic acid moiety, making it a versatile click chemistry reagent and a valuable building block for polymer and materials science. Its primary value lies in its ability to undergo highly selective Huisgen 1,3-dipolar cycloaddition reactions with alkynes, enabling efficient bioconjugation and surface functionalization. This compound is essential for researchers and manufacturers in the pharmaceutical, biotech, and advanced materials sectors who require reliable, high-purity intermediates for synthesizing drug conjugates, modifying biomolecules, or creating functionalized polymers and surfaces.

Application

• Click Chemistry Reagent: Key intermediate for Huisgen cycloaddition (copper-catalyzed or strain-promoted) to create triazole linkages with alkynes in drug discovery and bioconjugation.
• Polymer & Materials Science: Building block for synthesizing functional polymers, dendrimers, and surface coatings via azide-alkyne coupling.
• Bioconjugation & Probe Synthesis: Used to attach labels, dyes, or other molecules to proteins, peptides, and other biomolecules for diagnostic and research applications.
• Pharmaceutical Intermediates: Serves as a precursor in the synthesis of more complex active pharmaceutical ingredients (APIs) and prodrugs.
• Surface Modification: Functionalizes nanoparticles, glass, silicon, and other material surfaces to introduce specific chemical properties or bioactivity.
• Crosslinking Agent: Employed in the creation of hydrogels, polymer networks, and other crosslinked materials with tailored mechanical properties.
