8ARM PEG Raw Materials (hexaglycerol core)


PEG products with additional MW may be made to order, please contact us for details


8ARM PEG Raw Materials from JenKem Technology are high quality PEGs with very low polydispersity, suitable for further derivatization into PEG derivatives and hydrogels, prepared by ethoxylation of hexaglycerol. The reported molecular weight of the multi-arm PEGs is the sum of the PEG molecular weights of each arm. The number of ethylene oxide units in the PEG chain may not be equal for all arms.

8ARM PEGs with molecular weights and branching not listed in our online catalog may be available by custom synthesis. Please inquire at tech@jenkemusa.com about pricing and availability.

8ARM-PEG-OH 10kDa, 15kDa, 20kDa, 40kDa ≥ 95% ≤ 1.12


JenKem Technology also offers 8ARM(TP)-PEGs with tripentaerythritol core as an alternative to 8ARM PEGs with hexaglycerol core. 8ARM(TP)-PEGs have a higher purity as evidenced by MALDI compared with the generic 8ARM-PEGs with a hexaglycerin core.
