Properties

Description

This protected derivative possesses a terminal thiol group and a tert-butyl (t-butyl) protected carboxyl group joined by a PEG3 spacer. The thiol group enables specific attachment to thiophilic surfaces or reactions with electrophiles. Acidic treatment removes the t-butyl group to unmask a free carboxylic acid. The PEG3 chain imparts aqueous compatibility.
