MAL-PEG-OH (maleimide Polyethylene Glycol Hydroxyl)

MAL-PEG-OH (maleimide polyethylene glycol hydroxyl) is a linear heterobifunctional peg reagent with maleimide and hydroxyl. Mal-peg-oh is a useful PEG spacer crosslinker. Maleimide reacts with mercaptan, SH, mercapto or mercapto, and hydroxyl can react with carboxylic acid. Mal-peg-oh can also be used to synthesize PEGylated block copolymers, such as PLA-PEG (poly-L-lactic acid co polyethylene glycol) and PCL-PEG (polycaprolactone co polyethylene glycol), lactide polymerization initiated by hydroxyl or caprolactone. Maleimide contains reactive C = C double bond and is sensitive to light or oxygen.
