4-Arm PEG-succinic acid (4-arm PEG-SA) is a multiarmed PEG derivative characterized by four terminal carboxylic acid groups attached to a pentaerythritol core. It features a C2 hydrocarbon ester linkage connecting the PEG to the succinic acid carboxyl groups, facilitating reversible PEGylation. This versatile structure allows for efficient reactions with amine groups using peptide coupling reagents such as NHS, DCC, and EDC, making 4-arm PEG-SA an ideal candidate for bioconjugation and targeted drug delivery applications.
