8ARM PEG Raw Materials (tripentaerythritol core)


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


8ARM PEG (TP) Raw Materials from JenKem Technology are prepared by ethoxylation of tripentaerythritol and are suitable for further derivatization into PEG derivatives. 8ARM(TP)-PEGs with tripentaerythritol core have a higher purity as evidenced by MALDI compared with the generic 8 arm PEG Hydroxyl with hexaglycerin core.


The total molecular weight of the multi-arm PEGs is the sum of the molecular weights of all the arms. The number of ethylene oxide units in the PEG chain may not be equal for all arms.

Multi-arm PEG alcohol with molecular weights and branching not listed in our online catalog may be available by custom synthesis. Please contact us for details.
