General description

N-(2-Aminoethyl)maleimide trifluoroacetate salt is a thiol reactive cross-linking agent used in the preparation of heparin hydrogels

Application

N-(2-Aminoethyl)maleimide trifluoroacetate salt commonly utilized:
  • As a crosslinking agent to form covalent bonds between polymeric precursors
  • In the synthesis of maleimide-functionalized heparin hydrogels by introducing maleimide functional groups to molecules, enabling subsequent bioconjugation
  • In the synthesis of N-(2-{3-Iodobenzoyl}aminoethyl)maleimide and N-(2-{3-(tri-n-Butylstannyl)benzoyl}aminoethyl)maleimide
  • As a building block in the synthesis of maleimide-functionalized cymantrenyl derivatives

Other Notes

Heterobifunctional linker for introducing a maleimide function into the widely used NOSu-modified fluorescent labels.
