Description

Amino-PEG5-t-butyl ester is a PEG molecule consisting of an amino group and a t-butyl protected carboxyl group. 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.The hydrophilic PEG spacer increases solubility in aqueous media.
