8-Arm PEG-Hydrazide

Synonyms: Eight-Arm polyethylene glycol-Hydrazide; Eight-Arm PEG-Hydrazide

8-Arm polyethylene glycol-Hydrazide (8-Arm PEG-Hydrazide) is a multiarm PEG derivative with hydrazide groups at each terminal of the eight arms connected to one hexaglycerol core. It is a white solid and soluble in most organic solvents and has good solubility in water. It needs to be frozen, thawed slowly before use, and filled with nitrogen after use. Hydrazine-functionalized polyethylene glycol is an active polyethylene glycol derivative, which can modify proteins, polypeptides and other materials by carboxyl group (-COOH) or other amine active chemical groups. It also reacts quickly with carbohydrate residues. Eight arm polyethylene glycol derivatives have a variety of active groups and can be used to modify a variety of materials.
