(NH2) 7-8ARM PEG Nor Heterogeneous Multi arm Polyethylene Glycol

application

(NH ₂) 7-8ARM PEG Nor is an eight armed star shaped PEG, with seven arm ends containing free amino groups (- NH ₂) and one arm end containing a norbornene orthogonal reactive functional group.

1. 8-arm PEG (skeleton)

Introduction:Eight arm star shaped polyethylene glycol（8-arm PEG hydrophilic polymer skeleton.

Features:Highly hydrophilic, strong flexibility, good steric hindrance and shielding, and high biocompatibility.

Function:As a multifunctional spacer arm/linker， Improve solubility, prolong circulation, and reduce non-specific adsorption.

2. Amine (- NH ₂) × 7 (heptaarm amino)

Introduction:The seven arm ends are free amino groups（- NH ₂) nucleophilic reaction site.

Features:Highly reactive and easily susceptible to carboxyl groups/Acid anhydride/activated ester acylation.

Function:Used for multi site covalent coupling, drug loading grafting, or material cross-linking network construction.

3. Norbornene (Nor) × 1 (single arm de icing graphene)

Introduction:One end of the arm is composed of ice flakes（Norbornene is a bioorthogonal reactive group.

Features:Can participate in thiol groups-Vinyl click or Diels Alder orthogonal addition does not interfere with amino reactions.

Function:Used for targeted ligand, probe, or functional molecule introduction to achieve orthogonal functional integration.
