Methoxy PEG5 Hydroxyl


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


Monodisperse Methoxy PEG5 Hydroxyl reagent with superior quality specification of ≥ 95% Purity.

JenKem Technology manufactures high quality monodisperse Methoxy PEG (5, 6, 7, 8, 9, or 10) Hydroxyl products via very reproducible chemical reactions. JenKem’s monodisperse Methoxy Hydroxyl PEGs lack the polydispersity of traditional PEG polymers and retain the polyethylene glycol’s good solubility in water, while offering to PEGylated drugs the same PEG benefits of reduced aggregation and immunogenicity, and increased hydrodynamic volume. Monodisperse Methoxy PEG5 Hydroxyl is stable and can be activated.

JenKem Technology offers online monodisperse Methoxy PEG5 Hydroxyl with MW 252.2 Da (M-PEG5-OH) and Methoxy PEG6 Hydroxyl with MW 296.2 (M-PEG6-OH), in 5g and 25g packing sizes. To order Methoxy PEG7 Hydroxyl (M-PEG7-OH), Methoxy PEG8 Hydroxyl (M-PEG9-OH), Methoxy PEG9 Hydroxyl (M-PEG9-OH), Methoxy PEG10 Hydroxyl (M-PEG10-OH), Methoxy PEG11 Hydroxyl (M-PEG11-OH), and Methoxy PEG12 Hydroxyl (M-PEG12-OH) please contact us for a quote. Discrete Methoxy Hydroxyl PEGs with different MW (or different number of -CH2-CH2-O- units) may be available by custom synthesis, please email us at for details on custom PEGs. JenKem Technology provides repackaging services for an additional fee, please contact us if you require a different package size than our catalog selection.
