- Description
NH2-PEG4-CH2CH2COOtBu is a monodisperse, heterobifunctional PEG reagent with an amino group and a tert-butyl-protected carboxyl group. Its hydrophilic PEG spacer supports aqueous solubility. The amino terminus can react with carboxylic acids, activated NHS esters, ketones and aldehydes, while acidic conditions can remove the tert-butyl protection.
This reagent serves as a building block for bioconjugation and chemical biology synthesis, including small-molecule and biomolecular conjugates. Applications include linker construction for antibody-drug conjugates, peptide-drug conjugates and PROTAC molecules. The listed purity is ≥95%.
