Poly(ethylene oxide), 4-arm, succinimidyl glutarate terminated
Poly(ethylene oxide), 4-arm, succinimidyl glutarate terminated (CAS: 154467-38-6) is a branched polymer featuring four arms of polyethylene oxide terminated with succinimidyl glutarate groups. Supplied with an average molecular weight of approximately 10,000 g/mol (Mn) and a low polydispersity (Mw/Mn <1.2), this material is particularly useful in biodegradable drug delivery applications due to its functional end groups. It is stored under refrigeration at 2-8°C.
