4-Arm PEG-MAL, a multiarmed PEG derivative, features maleimide groups at each terminal connected to a pentaerythritol core. Maleimide selectively reacts with thiol groups via Michael addition, forming stable thioether bonds. This compound is valuable for site-specific protein and peptide modification.
