Iodoacetic acid is used as a reagent for the modification of sulfhydryl groups in organic synthesis. It reacts with cysteine moiety in proteins to prevent the re-formation of disulfide bonds during protein sequencing. It is also used as a general reagent in acylation reactions as well as in glycopeptide synthesis.
