Halogen PEGs (Bromide, Iodoacetamide)

Polysciences’ Halogen PEGs (Bromide, Iodoacetamide) collection offers specialty polyethylene glycol derivatives terminated with either halogen (bromide) or iodoacetamide reactive groups. These materials provide efficient coupling of biomolecules, surfaces or nanoparticles via thiol-specific reaction (iodoacetamide) or nucleophilic substitution (bromide). Available in modular molecular weights and reactive end-groups, these PEG linkers support hydrogel formation, nanomaterial functionalisation, protein labelling and surface engineering workflows.
