Boc/Fmoc PEG

Monodispersed Boc-PEG and Fmoc-PEG are classes of PEG linkers protected by Boc or Fmoc groups, respectively. These protecting groups can be removed under acidic conditions to generate a free amine group, essential for various bioconjugation and pharmaceutical applications. The monodispersed nature of these PEG linkers ensures uniformity and precise control over their molecular weight, enhancing their performance and reliability in drug delivery, diagnostics, and biomedical research.

Biopharma PEG offers a wide range of monodispersed Boc/Fmoc PEG linkers from lab to commercial scale in both non-GMP and GMP grades. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
