Description

9-Azidononanoic Acid is a bifunctional organic compound featuring a carboxylic acid and an azido group, making it a versatile building block for click chemistry and bioconjugation. Its primary value lies in its ability to serve as a linker for the site-specific modification of biomolecules, polymers, and surfaces under mild, aqueous conditions. This product is essential for researchers and manufacturers in pharmaceutical development, proteomics, materials science, and diagnostic assay production who require reliable, high-purity chemical tools.

Application

• Bioconjugation and Protein Labeling: Used to introduce azide handles onto peptides, proteins, or antibodies for subsequent click chemistry reactions with alkynes.
• Polymer Functionalization: Serves as a monomer or post-polymerization modifier to incorporate reactive azide groups into polymer backbones for creating smart materials.
• Surface Modification: Applied to functionalize nanoparticles, chips, or beads with azido groups to enable the immobilization of biomolecules or catalysts.
• Chemical Probe Synthesis: A key intermediate in the synthesis of activity-based probes (ABPs) and photoaffinity labels for target identification in drug discovery.
• Lipid and Membrane Research: Incorporated into lipid analogs to study membrane dynamics, trafficking, and protein-lipid interactions via bioorthogonal tagging.
• Diagnostic Reagent Development: Utilized in the fabrication of diagnostic components, such as modified antigens or antibodies, for assay platforms like ELISA and lateral flow tests.

Quality Control

Our 9-Azidononanoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistent performance for sensitive applications like bioconjugation. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation and degradation. Allow the container to reach room temperature in a desiccator before opening to prevent condensation and moisture uptake.
