Description

5-Azido-Pentanoic Acid Ethyl Ester is a versatile bifunctional organic compound featuring both an azide group and an ester moiety, making it a valuable click chemistry reagent and synthetic intermediate. Its primary value lies in its ability to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, enabling efficient and selective bioconjugation and polymer modification. This compound is essential for researchers and manufacturers in pharmaceutical development, materials science, and biotech, where it is used to create novel drug conjugates, functionalize surfaces, and synthesize advanced polymers.

Application

• Click Chemistry Reagent: A key building block for CuAAC (copper-catalyzed azide-alkyne cycloaddition) reactions to create triazole linkages.
• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, targeted drug delivery systems, and bioconjugates.
• Polymer & Materials Science: Functionalization of polymers, dendrimers, and surfaces to introduce specific chemical handles or modify material properties.
• Bioconjugation: Labeling of proteins, antibodies, oligonucleotides, and other biomolecules for diagnostics, imaging, and therapeutic applications.
• Chemical Probe Synthesis: Creation of activity-based probes (ABPs) and other tools for chemical biology and proteomics research.
• Cross-linking Agent: Used to create covalent cross-links between molecules in hydrogel formation and material cross-linking.

Quality Control

Our 5-Azido-Pentanoic Acid Ethyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to the presence of the organic azide functional group, it is recommended to store away from heat, sparks, and open flames. Keep container tightly sealed when not in use to prevent moisture absorption and decomposition.
