Carboxyl PEG8 Carboxyl

Monodisperse Acetic Acid PEG8 Acetic Acid reagent with superior quality specification of ≥ 95% Purity.

Monodisperse Acetic Acid PEG8 Acetic Acid from JenKem Technology (a.k.a. discrete diCarboxy PEG8, Carboxyl PEG8 Carboxyl, diAcetic Acid PEG8, diCM PEG8, diCarboxylPEG8 or diAA PEG8) is a single molecule homobifunctional PEG employed for amine PEGylation.  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 Carboxyl PEG Carboxyl products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. JenKem’s monodisperse Carboxyl PEG Carboxyl 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 offers monodisperse Acetic Acid PEG8 Acetic Acid with MW 486.5 Da (CM-PEG8-CM) and cetic Acid PEG12 Acetic Acid with MW 662.7 Da (CM-PEG12-CM), in 1g and 5g packing sizes.  Discrete PEG diCarboxyl with different numbers of -CH2-CH2-O- units, such as Acetic Acid PEG4 Acetic Acid (CM-PEG4-CM) 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.
