Propionic Acid PEG12 Propionic Acid


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


Monodisperse Propionic Acid PEG12 Propionic Acid reagent with superior quality specification of ≥ 95% Purity.

Monodisperse Propionic Acid PEG12 Propionic Acid from JenKem Technology (discrete diPA PEG12, PEG12 diPropanoic Acid, or PEG12 dicarboxyl) is a single molecule homobifunctional PEG employed for amine PEGylation. Monodisperse PEG diPropionic Acid is more stable than PEG-diSCM. JenKem Technology’s discrete PEG diPropionic Acid products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. JenKem’s monodisperse diPropionic Acid 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. 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 offers monodisperse Propionic Acid PEG Propionic Acid with MW 514.6 Da (PA-PEG8-PA) and MW 690.8 Da (PA-PEG12-PA), in 1g and 5g packing sizes. DiPropionic Acid PEGs with different number of -CH2-CH2-O- units, such as Propionic Acid PEG4 Propionic Acid (PA-PEG4-PA), 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.
