Heretic multi armed polyethylene glycol (NH2) 7-8ARM-PEG-N3

application

1. Basic Definition

An asymmetric multifunctional derivative of 8-arm star shaped polyethylene glycol (8-arm PEG)

End group composition: 7 amino groups (NH ₂)+1 azide (N ∝)

Mainly used for click coupling, cross-linking construction, and targeted functionalization

2. Structural features

Star shaped eight arm core provides high-density reaction platform

7: Asymmetric end group design enables selective reactions of different arms, suitable for constructing complex bifunctional or multifunctional systems

PEG backbone has excellent water solubility, flexibility, and biocompatibility

3. Terminal function

NH ₂ (amino, 7):Can participate in amidation, grafting modification, electrostatic binding, surface charge regulation, commonly used to connect targeted molecules, dyes, peptides, etc., or participate in multi-point crosslinking

N3 (azide, 1):Classic click reactive groups are used for efficient coupling of CuAAC or SPAAC (copper free click) with alkynyl molecules, characterized by high specificity, mildness, rapidity, and high yield

4. Typical applications

Hydrogel cross-linking or network construction (Dobby NH ₂ participates in cross-linking, and N ∨ directionally introduces functional molecules)

Biomolecular coupling (protein/peptide/nucleic acid/targeted ligand modification)

Nanomaterials or surface modification (charge control, functional grafting)

Functionalization of drug carriers or construction of multi module materials

5. Main advantages

Multiple reaction sites with high density (eight arm structure)

Click to separate from conventional chemical modification sites, with strong controllability

Has high water solubility, low toxicity, low immunogenicity, and good in vivo compatibility

Accurate functional design suitable for complex systems
