Methoxy PEG Hydrazide


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


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

Methoxy PEG Hydrazide (MPEG Hydrazine or MPEG Hydrazide) from JenKem Technology is a high quality aldehyde reactive PEG, ketone reactive PEG, and carboxyl reactive PEG. The hydrazide group is carbonyl reactive and it is usually employed in PEGylation of glycosylated sites of proteins. JenKem Technology offers Methoxy PEG Hydrazide with MW 5,000 Da (M-HZ-5000), MW 10,000 Da (M-HZ-10K), MW 20,000 Da (M-HZ-20K) and MW 30,000 Da (M-HZ-30K), in 1g and 10g packing sizes.

Different MW of Methoxy PEG Hydrazide carbonyl reactive 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.

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