Properties

Description

This short heterobifunctional reagent pairs a free sulfhydryl (thiol) group with a carboxylic acid terminal via a tetraethylene glycol (PEG4) spacer. The free thiol reacts with maleimides, haloacetamides, or gold surfaces. The carboxylic acid group permits amidation reactions with primary amines. The PEG4 chain delivers good polarity and compact spatial reach.
