Iodonitrotetrazolium chloride Usage And Synthesis

Chemical Properties

slightly yellow powder

Uses

Electron acceptor for the colorimetric assay of various dehydrogenases.

Definition

ChEBI: An organic chloride salt having iodonitrotetrazolium as the counterion.

Purification Methods

Recrystallise the chloride from H2O, aqueous EtOH or EtOH/Et2O. Alternatively, dissolve it in the minimum volume of EtOH and add Et2O; or dissolve it in hot H2O (charcoal), filter and precipitate it by adding conc HCl. Filter the solid off and dry it at 100o. Its solubility in H2O at 25o is 0.5%, and in hot MeOH/H2O (1:1) it is 5%. [Fox & Atkinson J Am Chem Soc 72 3629 1950, Beilstein 26 III/IV 1776.]
