PEG dibromide, Mp 3000

PEG Dibromide (Br-PEG-Br) is a bifunctional polyethylene glycol (PEG) derivative featuring two terminal bromine (-Br) groups, making it a highly reactive intermediate for nucleophilic substitution, atom transfer radical polymerization (ATRP), and polymer functionalization. The bromine groups enable precise end-group modifications, allowing PEG dibromide to serve as a macroinitiator for block copolymer synthesis and crosslinking reagent for polymeric networks.

Applications:

Polymer & Hydrogel Crosslinking: Reacts via nucleophilic substitution to form tailored polymeric architectures.
ATRP & Controlled Radical Polymerization: Functions as a macroinitiator for block copolymer synthesis.
Surface Functionalization: Introduces reactive end groups for biomaterial and nanoparticle modification.
Biomedical & Drug Delivery Systems: Used in controlled drug release formulations and hydrogel formation.
