2,3,5-Triphenyl-2H-tetrazolium chloride is used as a dye in cell biological studies.
2,3,5-Triphenyltetrazolium chloride is a selective serotonin 5-HT4 receptor agonist and 5-HT3 gastrointestinal prokinetic agent for functional dyspepsia
In analytical chemistry as a sensitive reagent for reducing sugars, and to distinguish between a-ketols and simple aldehydes. For staining plant and animal tissue. Germination indicator in testing the ability of seeds to germinate: G. Lakon, Ber. Dtsch. Bot. Ges. 60, 299, 434 (1942). In histochemical studies. In determination of antibiotics; of dehydrogenases.
ChEBI: An organic chloride salt having 2,3,5-triphenyltetrazolium as the counterion.
2,3,5-Triphenyltetrazolium chloride is a colorless water-soluble dye. In the mitochondria of living cells, it is reduced to a deep red, water-insoluble compound (formazan). 2,3,5-Triphenyltetrazolium chloride helps to distinguish between viable and infarcted brain tissue after stroke.
Crystallise TTZ from EtOH or CHCl3, and dry it at 105o. [Beilstein 26 H 363, 26 II 216, 26 III/IV 1774.]
