Hydroxyl PEG36 Hydroxyl


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


Monodisperse Hydroxyl PEG36 Hydroxyl reagent with superior quality specification of ≥ 95% Purity.

Monodisperse Hydroxyl PEG36 Hydroxyl from JenKem Technology (single molecule PEG36 dihydroxyl, or hexatriacontaethylene glycol, MW=1603.9 Dalton) is a homobifunctional PEG for PEGylation, with stable HO groups that can be activated. Monodisperse homobifunctional PEG derivatives from JenKem Technology are high quality crosslinkers for PEGylation of proteins and peptides, nanoparticle and surface modifications. Conjugation with homobifunctional PEGs provides an increased drug load compared to pegylation using linear PEGs. JenKem Technology’s monodisperse discrete PEG dihydroxy products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. JenKem’s monodisperse dihydroxyl PEGs retain the polyethylene glycol’s good solubility in water, while offering to PEGylated drugs the same PEG benefits of reduced aggregation and immunogenicity, and increased hydrodynamic volume.

JenKem Technology also offers monodisperse Hydroxyl PEG Hydroxyl with MW 370.5 Da (HO-PEG8-OH), MW 414.5 Da (HO-PEG9-OH), and MW 546.7 Da (HO-PEG12-OH). Dihydroxyl PEGs with different numbers of -CH2-CH2-O- units 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.
