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


Methoxy PEG Nitrophenyl Carbonate with superior quality specification of ≥90% Substitution.

Methoxy PEG Nitrophenyl Carbonate from JenKem Technology is a linear Amine Reactive PEG with stable carbonate linker. Methoxy PEG Nitrophenyl Carbonate is reactive towards the amino group of lysine(s) by means of stable urethane linkages, with a longer hydrolysis half-life compared with M-PEG-SCM. The amine pegylation reaction releases p-nitrophenol which can be easily traced by UV spectroscopy. JenKem Technology provides Methoxy PEG Nitrophenyl Carbonate with molecular weight 10000Da (M-NPC-10K) and 20000Da (M-NPC-20K), in 1g and 10g packaging.

Different MW of Methoxy PEG Nitrophenyl Carbonate products 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. Other related linear Amine Reactive carbonate PEG products are available: linear carbonate PEGs.
