Monodisperse Amino-PEG3-t-butyl ester (NH2-PEG3-CH2CH2COOtBu) is a heterobifunctional PEG linker containing an amino (NH2) group with 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 group can be deprotected under acidic conditions.
