Properties

Description

This compact building block couples a protected thiol (S-acetyl) group to a carboxylic acid terminal via a triethylene glycol (PEG3) spacer. The S-acetyl group can be selectively deprotected to yield a free sulfhydryl group. The carboxylic acid terminal undergoes efficient amide coupling with primary amines. The short PEG3 chain maintains adequate polarity.
