Properties

Description

This heterobifunctional compound incorporates a thiol group and a terminal carboxylic acid connected by a monodisperse PEG3 chain. The thiol group participates in thiol-ene click reactions or disulfide bond formation. The carboxylic acid group couples with primary amines using EDC and HATU reagents. The hydrophilic PEG3 linker improves water solubility.
