7. Single Molecule PEGs PUREBRIGHT® Series

We have the technology to synthesize PEG molecules with a specific number of ethylene oxide units, providing a highly pure product that has a single molecular weight and length.  The purity of our products come from purification techniques that we have accumulated from the development of various PEGs.

In addition, we can supply specific length PEGs at various molecular weights and with select architectures (linear or branched type) and functional groups such as maleimide, Boc, azide, DBCO, as well as amino group and carboxyl group by applying our synthetic techniques developed for standard activated PEGs.
