Methoxy PEG5 Acrylate


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


Monodisperse Methoxy PEG5 Acrylate reagent with superior quality specification of ≥ 90% Purity.

Monodisperse Methoxy PEG Acrylate (M-PEG Acrylate, or Acryl PEGs) from JenKem Technology are discrete thiol-reactive PEG, reacting with sulfhydryl groups via Michael addition reactions; and they can also react with amines. Acrylate groups are typically involved in vinyl polymerization or co-polymerization. JenKem Technology’s single molecule Methoxy PEG Acrylate products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. JenKem’s monodisperse Acrylate 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 Acrylate (monodisperse Acryl PEG) is available with MW 306.3 (M-PEG5-ACLT) and MW 350.4 Da (M-PEG6-ACLT), in 1g and 5g packing sizes. JenKem Technology provides repackaging services for an additional fee, please contact us if you require a different package size than our catalog selection.

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