Iodonitrotetrazolium (chloride)

Iodonitrotetrazolium (INT) is a monotetrazolium salt used as an indicator dye. It is reduced to an insoluble formazan that is used as a vital dye or indicator of cellular redox activity. Reduction commonly results from the activity of dehydrogenases, although non-enzymatic electron transfer reactions can occur in the presence of an intermediate electron acceptor. INT is commonly used to measure the respiratory activity of microorganisms in a variety of contexts.Formal Name: 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyl-2H-tetrazolium, monochloride.
