Description

Azido-Peg8-Azide is a heterobifunctional polyethylene glycol (PEG) linker featuring terminal azide groups. This compound is essential for facilitating click chemistry reactions, specifically copper-catalyzed azide-alkyne cycloaddition (CuAAC), to create stable triazole linkages. It is primarily used by researchers and manufacturers in the pharmaceutical, bioconjugation, and materials science industries for constructing complex molecular architectures, modifying surfaces, and developing drug delivery systems. Its hydrophilic PEG spacer enhances solubility and reduces immunogenicity in biological applications.

Application

• Bioconjugation and antibody-drug conjugate (ADC) linker synthesis.
• Surface functionalization of nanoparticles and biomaterials via click chemistry.
• Polymer and dendrimer synthesis as a versatile building block.
• Development of hydrogels and cross-linked networks for tissue engineering.
• Preparation of PEGylated therapeutics and diagnostic probes.
• Solid-phase peptide synthesis (SPPS) and combinatorial chemistry.
• Labeling of biomolecules (proteins, oligonucleotides) for imaging and tracking.
• Chemical biology tool for studying protein-protein interactions and cellular processes.

Quality Control

Our Azido-Peg8-Azide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your research and development 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) and should be handled under anhydrous conditions to maintain stability. For long-term storage, consider storing under an inert atmosphere.
