Large-Scale Monodisperse PEG Products
Biochempeg continuously expands its capability to provide large-scale manufacture of
high purity monodisperse PEG derivatives with an extensive variety of functional groups,
in both non-GMP and GMP grade.
Monodisperse PEG retains the good water solubility of polyethylene glycol, and provides
the same PEG benefits for PEGylated drugs, namely reducing aggregation and
immunogenicity, and increasing hydrodynamic volume.
The following are some examples of our monodisperse PEG products with
purity >95% that have been scaled up to kilogram scale batch size.
