Catalog No. : PJK-402
Product Name : 4-Arm PEG-OH, MW 20k
Description :

4-Arm PEG-OH is a multi-arm polyethylene glycol with hydroxyl groups at each terminal of the four arms. Pentaerythritol core is used in 4arm PEG raw materials and derivatives. The indicated molecular weight of the multi-arm PEG is the sum of the molecular weights of all the arms. It can be used to prepare functional PEG reagents or in sol-gel chemistry to make silica-related hydrogel.
