white to light yellow crystalline powder
Used as a general reagent in acylation reactions. A byproduct formed in treated waters, and found in marine life.
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.
ChEBI: A haloacetic acid that is acetic acid in which one of the hydrogens of the methyl group is replaced by an iodine atom.
Colorless or white crystals.
May be sensitive to heat, light, and air. Water soluble
Iodoacetic acid reacts vigorously with bases and is corrosive.
Flash point data for Iodoacetic acid are not available, but Iodoacetic acid is probably non-flammable.
Iodoacetic acid (IAA) blocks the thiol group of cysteine. IAA inhibits glyceraldehyde-3-phosphate dehydrogenase (G3PDH) by interacting with sulfhydryl group of the active site cysteine. IAA inhibits the progression of solid Ehrlich carcinoma. IAA is one of the iodinated disinfection byproducts in drinking water. It is cytotoxic to mammalian cells.
Crystallise it from pet ether (b 60-80o) or CHCl3/CCl4. [Beilstein 2 IV 534.]
