Properties

Description

This protected heterobifunctional reagent pairs a 2-pyridyldithio domain with a tert-butyl (t-butyl) ester via a diethylene glycol (PEG2) spacer. The 2-pyridyldithio group reacts with thiols via disulfide exchange. The t-butyl ester provides acid-cleavable protection for the carboxylic acid handle. The short PEG2 linker maintains tight physical distance.
