6ARM PEG Raw Materials (dipentaerythritol core)


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


JenKem Technology’s 6arm PEG raw materials (6ARM-PEG-OH, or 6arm PEG Hydroxyl) are high quality PEGs with very low polydispersity that can be derivatized and crosslinked into PEG hydrogels. JenKem Technology’s 6 arm PEGs are synthesized by ethoxylation of dipentaerythritol (6ARM PEG). The total molecular weight reported for the JenKem 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.

Multi-arm star PEG raw materials 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.
