Methoxy PEG5 Propionic Acid


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


Monodisperse Methoxy PEG5 Propionic Acid (Methoxy PEG5 Propanoic Acid) reagent with superior quality specification of ≥ 95% Purity.

JenKem Technology manufactures high quality monodisperse Methoxy PEG Propionic Acid products that can be activated for amine PEGylation. JenKem Technology’s discrete PEG Propionic Acid products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. JenKem’s monodisperse Propionic Acid PEGs 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 PEG Propionic Acid is more stable than M-PEG-SCM.

JenKem Technology offers monodisperse Methoxy PEG5 Propionic Acid with MW 324.5 Da (M-PEG5-PA) and Methoxy PEG6 Propionic Acid with MW 368.2 (M-PEG6-PA), in 1g and 5g packing sizes. Methoxy PEG8 Propionic Acid and Methoxy PEG10 Propionic Acid, Methoxy PEG6 Acetic Acid (M-PEG6-COOH) and monodisperse Methoxy Propionic Acid PEGs with different MW (or different number of -CH2-CH2-O- units) are made-to-order, 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. Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
