4arm PEG Acrylate


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


4arm PEG Acrylate reagent with superior quality specification of ≥ 95% Substitution.

JenKem Technology’s 4arm PEG Acrylate derivatives can be cross-linked into PEG hydrogels. PEG hydrogels have a variety of applications in medical devices and regenerative medicine, and are especially of interest for controlled release of drugs, for 2D and 3D cell culture, and for wound sealing and healing. JenKem Technology’s 4 arm PEGs are synthesized by ethoxylation of pentaerythritol. The number of ethylene oxide units in the PEG chain may not be equal for all arms. The total molecular weight reported for the JenKem multi-arm PEGs is the sum of the PEG molecular weights of each arm.

Multi-arm star PEG products with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom PEG synthesis. Please inquire at tech@jenkemusa.com about pricing and availability of custom PEGs.

Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
