2-Iodosobenzoic acid Chemical Properties, Uses, Production
Chemical Properties
White powder
Uses
1-Organosulfonyloxy-1, 2-benziodoxol-3-(1H)-ones (3, 4, 5) can be prepared in one step from 2-iodosobenzoic acid and the corresponding sulfonic acids. 2-carboxydiphenyliodonium salts was prepared by the acid-catalyzed condensation of 2-iodosobenzoic acid with benzene, mesitylene, and cyclohexylbenzene.
Definition
ChEBI: A benzoic acid compound having an iodosyl substituent at the ortho-position.
Biological Activity
2-Iodosobenzoic acid (IBA) may be used to study enzyme structure and activity. IBA is used as an oxidant which oxidizes vicinal sulfhydryls to disulfides (cysteine residues) within enzymes leading to their inactivation or conformational changes. IBA is also used to cleave tryptophanyl peptide bonds.
Purification Methods
Crystallise the acid from EtOH and dry it in vacuo.[Beilstein 9 H 363.]
