Y-shape PEG Amine


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


Y-shape PEG Amine with superior quality specification of ≥95% Substitution.

Y-shape PEG Amine from JenKem Technology is an amine 2arm Y-shaped branched PEG that attaches to substrates via stable linkages, such as amide, urethane, urea, or secondary amine. The Amine group of Y-shape PEG Amine is more reactive towards acylating agents than the hydroxyl group and it readily undergoes reductive amination reactions. JenKem proprietary Y-shape PEGs are more selective than linear PEGs, due to their sterically bulky structure.

JenKem Technology offers Y-shape PEG Amine with MW 40000 (Y-NH2-40K), in 1g and 10g packing sizes. Different MW of Y-shape PEG NH2 products may be available by custom synthesis, please email us at tech@jenkemusa.com 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.
