Description

Azido-Peg3-Azide is a bifunctional polyethylene glycol (PEG) linker featuring terminal azide groups. This compound is a critical reagent in click chemistry, specifically copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling the efficient and bioorthogonal conjugation of biomolecules, polymers, and surfaces. It is essential for researchers and manufacturers in bioconjugation, pharmaceutical development, and materials science who require reliable, high-purity linkers to create stable, functionalized constructs for drug delivery systems, diagnostic probes, and advanced polymeric materials.

Application

• Bioconjugation and Antibody-Drug Conjugate (ADC) Development: Used as a heterobifunctional crosslinker to attach cytotoxic drugs, fluorophores, or other payloads to antibodies, proteins, or peptides.
• Polymer and Dendrimer Synthesis: Serves as a versatile building block for creating functionalized PEG-based polymers, hydrogels, and dendritic structures via click chemistry.
• Surface Functionalization and Material Science: Enables the modification of nanoparticles, biosensors, and other material surfaces with bioactive ligands or functional groups.
• Diagnostic Probe and Imaging Agent Preparation: Facilitates the labeling of targeting molecules (e.g., peptides, antibodies) with imaging agents (e.g., fluorescent dyes, radionuclide chelators).
• Chemical Biology and Proteomics: A key tool for labeling and studying biomolecules in living systems due to its bioorthogonal reactivity.
• Pharmaceutical Research: Used in the development of prodrugs and novel drug delivery platforms that require controlled release or targeted delivery mechanisms.
