Description

Azido-Peg9-Alcohol is a heterobifunctional polyethylene glycol (PEG) derivative featuring a reactive azide group at one terminus and a hydroxyl group at the other. This unique structure makes it an invaluable building block for creating custom linkers and spacers in bioconjugation and materials science. It is primarily used by researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors for developing targeted drug delivery systems, diagnostic agents, and functionalized surfaces.

Application

• Bioconjugation Linker: Used to covalently attach biomolecules (e.g., antibodies, peptides, oligonucleotides) to other entities like drugs, dyes, or solid surfaces via click chemistry.
• ADC (Antibody-Drug Conjugate) Development: Serves as a hydrophilic, flexible spacer to connect cytotoxic payloads to monoclonal antibodies, improving solubility and pharmacokinetics.
• PEGylation Reagent: The hydroxyl group can be further functionalized to introduce PEG chains onto proteins or nanoparticles, enhancing stability and reducing immunogenicity.
• Polymer and Materials Modification: Enables the introduction of azide functionality into polymers, hydrogels, or surfaces for subsequent click chemistry modifications.
• Diagnostic Probe Synthesis: Facilitates the construction of imaging probes and biosensors by linking targeting molecules to reporter groups.
• Cross-linking Agent: Used in the synthesis of cross-linked networks or dendrimers for specialized material properties.
