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


Methoxy PEG Succinimidyl Glutarate with superior quality specification of ≥95% Substitution.

Methoxy PEG Succinimidyl Glutarate (Methoxy PEG SG) is a high quality amine reactive methyl ether NHS PEG product from JenKem Technology. Methoxy PEG SG is a degradable  PEG with a cleavable ester linker between the PEG polymeric chain and the NHS ester. Linear NHS PEGs with a Cleavable Linker (degradable PEGs) are especially employed in controlled release drug development applications. Methoxy PEG Succinimidyl Glutarate reacts with the amine group of lysine(s) at pH 7-8, while the ester linkage is cleaved under regular ester cleaving reaction conditions. Methoxy PEG Succinimidyl Glutarate has a slightly longer hydrolysis half life compared to Methoxy PEG Succinimidyl Succinate. JenKem Technology offers Methoxy PEG SG with MW 5000 Da (M-SG-5000) and MW 20000 Da (M-SG-20K), in 1g and 10g packing sizes.

Different MW of Methoxy PEG Succinimidyl Glutarate products may be available by custom synthesis, please email us at for details on custom PEGs. Other linear NHS esters are available – please select other cleavable linker NHS PEGs; or stable linker NHS 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.
