8ARM-PEG Derivatives (tripentaerythritol core)

JenKem Technology’s patented 8arm(TP) star PEGs are synthesized by ethoxylation of tripentaerythritol. 8ARM(TP)-PEGs with tripentaerythritol core have a higher purity as evidenced by MALDI compared with the generic 8ARM-PEGs with a hexaglycerin core. 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 molecular weights of all arms.

Multi-arm star PEG products with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at tech@jenkemusa.com about pricing and availability. Bulk PEGs and GMP PEGs are available upon request. Please contact us for special bulk pricing.
