The compound INDT 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-(2,4-dinitrophenyl) tetrazolium bromide exhibits facile reduction to insoluble chromophoric formazan compared to the chromagen INT. INDT differs structurally from INT 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride by having 2,4-dinitrophenyl instead of phenyl at the 5-position on the tetrazolium ring. The compounds, including INDT, are useful as chromagens for histological staining, as well as in enzyme-amplified staining as a part of immunological or hybridization assays.
