Medchemexpress LLC DSPE-PEG3-azide | 97.0% | 977.30 | 50 MG
SDP

DSPE-PEG3-azide is an azide-containing lipid used to form micelles as nanoparticles for drug delivery. This click chemistry reagent contains an azide group, allowing it to undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with alkyne-containing molecules. It can also participate in strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with DBCO or BCN groups.

  • Azide containing lipid
  • Used to form micelles as nanoparticles for drug delivery
  • Click chemistry reagent
  • Undergoes copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with alkyne groups
