Mal-PEG-OH (MW 40000)

Mal-PEG-OH (MW 40000) (Maleimide-PEG-Hydroxy (MW 40000) ) is a linear heterobifunctional PEG product featuring maleimide and hydroxy groups. This compound can serve as a macromolecular initiator to generate amphiphilic diblock copolymers through the ring-opening polymerization of Lactate (Lactic Acid) . Such amphiphilic block copolymers are utilized in forming nanoparticles for active drug delivery systems.
