Description

Ethyl 11-Azidoundecanoate is a specialized bifunctional organic compound featuring both an ester and an azide group on a long aliphatic chain. This unique structure makes it a valuable click chemistry reagent and a versatile chemical building block for advanced material synthesis. It is primarily utilized by researchers and manufacturers in the pharmaceutical, polymer, and bioconjugation sectors to create novel polymers, drug conjugates, and functionalized surfaces.

Application

• Click Chemistry Reagent: Used in copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions for the synthesis of triazole-linked polymers, dendrimers, and small molecules.
• Polymer Modification: Serves as a functional monomer or post-polymerization modifier to introduce azide handles into polymer backbones for subsequent crosslinking or labeling.
• Bioconjugation & Probe Synthesis: Enables the site-specific labeling of biomolecules (proteins, peptides, oligonucleotides) with various tags, dyes, or drugs for diagnostic and therapeutic applications.
• Material Science: Used to functionalize surfaces (e.g., nanoparticles, silicon wafers, graphene) to create advanced coatings, sensors, and composite materials.
• Pharmaceutical Intermediate: Acts as a key synthetic precursor in the development of active pharmaceutical ingredients (APIs) and prodrugs.
• Lubricant & Surfactant Additive: Potential use as a functional additive to modify the properties of industrial lubricants and surfactants.
