Description

4ARM PEG Raw Materials from JenKem Technology are high quality PEGs with very low polydispersity prepared by ethoxylation of pentaerythritol, suitable for further derivatization into PEG derivatives and for hydrogel formation. The reported molecular weight of 4ARM-PEG-OH 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.

JenKem Technology also provides a 4ARM PEG GPC Calibration Standards kit (STD4ARMPEG) that includes 200mg each of 4ARM-PEG-2000, 4ARM-PEG-5000, 4ARM-PEG-10K, 4ARM-PEG-20K, and 4ARM-PEG-40K.

Multi-arm PEG raw products 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.
