Highly Pure,
Monodispersed
Polyethylene Glycol
(PEG) Products
While most PEG products are a mixture of different
molecular weights, PurePEG supplies mono-disperse,
single molecular weight molecules. Through our innovative
PurePEG TM technology, we have the ability
to manufacture high quality mono-disperse PEGs with
precise molecular weights in high purities.
Unlock Precision in Every Molecule
Our high-purity, monodisperse PEGs enable you
more reliable experiments, cleaner data, and faster breakthroughs.
Whether you’re developing next-generation therapeutics or pushing the boundaries of materials science, PurePEG provides the molecular tools to transform your ideas into groundbreaking realities.

WELCOME TO PurePEG
PEGs have earned their place in the biomedical field due to their
water solubility, non-toxicity, and non-immunogenicity properties.
They are widely used in research for bioconjugation, assays, and
bioorthogonal labeling purposes. To date, there are 12 PEGylated
drugs approved by the FDA for treatment of a number of chronic
diseases, with more approvals pending. PurePEG developed the
first acid functionalized PEG used in an FDA approved antibody-
drug conjugate (ADC drug) used to treat breast cancer. PEG’s
impact on biological therapies cannot be understated. Despite a
wider market of suppliers and manufacturers of PEG, PurePEG still
stands at the forefront with our unparalleled quality of PEG and
our ever-expanding PEG research and development
Supplying PEG reagents
with discrete molecular
weights, offering PEG
reagents with
up to min.99% purity
