Monodisperse Amino-PEG4-t-butyl ester (NH2-PEG4-CH2CH2COOtBu) is a heterobifunctional PEG reagent containing an amino (NH2) and a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl (Boc) can be deprotected under acidic conditions.
