Description

Azido-Peg11-Azide is a high-purity, heterobifunctional polyethylene glycol (PEG) linker featuring terminal azide groups. This compound is essential for creating stable, hydrophilic spacers in bioconjugation and materials science, enabling controlled cross-linking via click chemistry reactions. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors for developing drug delivery systems, hydrogels, and diagnostic reagents.

Application

• Bioconjugation linker for attaching biomolecules (e.g., proteins, peptides, antibodies) to surfaces, nanoparticles, or other polymers via copper-catalyzed or strain-promoted azide-alkyne cycloaddition (CuAAC/SPAAC).
• Critical reagent in the synthesis of PEGylated drug conjugates and antibody-drug conjugates (ADCs) to enhance solubility, prolong circulation time, and reduce immunogenicity.
• Building block for creating cross-linked hydrogels and biomaterials with tailored mechanical properties for tissue engineering and 3D cell culture applications.
• Surface functionalization agent for modifying nanoparticles, quantum dots, and microspheres to improve biocompatibility and enable subsequent bio-orthogonal labeling.
• Intermediate in the synthesis of complex dendrimers and multi-arm PEG derivatives for advanced therapeutic and diagnostic platforms.
• Tool compound in chemical biology for studying biomolecular interactions and developing novel biosensors through site-specific labeling strategies.

Quality Control

Our Azido-Peg11-Azide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and consistent performance for critical research and development applications. Certificates of Analysis (COA) with detailed specifications are provided to guarantee compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. For long-term storage, consider desiccation.
