Application

N-(2-Hydroxyethyl)maleimide can be used:
  • In the synthesis of (EFA)-based multifunctional oligoester resins with maleimides as end groups by reacting with 9,10-epoxy-18-hydroxyoctadecanoic acid (EFA) and dimethyl adipate catalyzed by Candida antarctica lipase B (CalB).
  • As an initiator in ring-opening polymerization of δ-valerolactone catalyzed by trifluoromethanesulfonimide.
  • In one-pot synthesis of bio-based polyurethane-imides by reacting with castor oil, eleostearic acid diethanol amide and isophorone diisocyanate.

N-(2-Hydroxyethyl)maleimide may be used to synthesize [2,2-bis(maleimidoethoxy)-
propane (BMEP)], a protein cross-linking reagent with potential application in constructing immunotoxins. It may also be used in preparing thermoresponsive self-healing polyurethanes with the shape-memory property.
