Description

Azido-Peg10-Azide is a heterobifunctional polyethylene glycol (PEG) linker featuring terminal azide groups. This compound is a critical reagent in bioconjugation and click chemistry, enabling the efficient, site-specific cross-linking of biomolecules and materials under mild, aqueous conditions. It is essential for researchers and manufacturers in pharmaceutical development, proteomics, and advanced material science who require precise and stable molecular assembly.

Application

• Bioconjugation and Antibody-Drug Conjugate (ADC) Development: Used as a linker to attach cytotoxic drugs, fluorophores, or other payloads to antibodies, proteins, or peptides.
• Click Chemistry Reactions: Serves as a key component in copper-catalyzed azide-alkyne cycloaddition (CuAAC) and strain-promoted azide-alkyne cycloaddition (SPAAC) for labeling and polymer synthesis.
• PEGylation and Surface Modification: Imparts hydrophilicity, reduces immunogenicity, and extends circulation half-life when used to modify therapeutic proteins, nanoparticles, or biomedical surfaces.
• Hydrogel and Biomaterial Fabrication: Acts as a cross-linking agent to create biocompatible hydrogels for drug delivery systems, 3D cell culture, and tissue engineering scaffolds.
• Diagnostic Reagent Synthesis: Employed in the development of diagnostic assays, biosensors, and imaging probes by linking recognition elements to signal reporters.
• Polymer and Dendrimer Synthesis: Functions as a versatile building block for constructing functionalized polymers and dendritic structures with precise architecture.
