Methoxy PEG Succinimidyl Hexanoate


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


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

JenKem Technology’s Methoxy PEG Succinimidyl Hexanoate (Methoxy PEG SHA) is a high quality amine reactive PEG product with a stable non-degradable linker between the PEG polymeric chain and the NHS ester. Methoxy PEG Succinimidyl Hexanoate reacts with the amine group of lysine(s) at pH 7-8. Methoxy PEG Succinimidyl Hexanoate has a longer hydrolysis half-life compared with M-PEG-SCM and M-PEG-SBA. JenKem Technology offers Methoxy PEG SHA with MW 5000 Da (M-SHA-5000), and MW 20000 Da (M-SHA-20K), in 1g and 10g packing sizes.

Different MW of Methoxy PEG SHA products may be available by custom synthesis, please email us at for details on custom PEGs. Other linear JenKem NHS ester PEGs are available – if interested please select stable linker NHS PEGs, carbonate linker stable NHS PEGs, or cleavable 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.
