2,3,5-Triphenyltetrazoliumchloride

2,3,5-Triphenyltetrazolium chloride TTC; Tetrazolium red; TPTZ; Tetrazole red Tetrazolium Red is used to visualise dehydrogenase enzyme activity. Initially the tetrazolium solution is colorless but changes to red when it comes into contact with hydrogen. Tetrazolium red is used in a biochemical viability test for seeds. The test relies on dehydrogenase enzymes to release hydrogen ions which subsequently reduce the colorless tetrazolium salt solution to a red compound called formazan. Living cells turn red, while dead cells remain colorless. Redox indicator used to detect cellular respiration. Primarily reduced by Complex I in mitochondria and, under anaerobic conditions, is completely reduced to an insoluble red 1,3,5-triphenylformazan. Typically used as a mitochondrial redox potential indicator for cell death. TTC is a redox indicator used to detect cellular respiration.

Properties: Solvated nearly colorless needles from alcohol or chloroform, dry at 105?. Turns yellow on exposure to light. Dec 243?. Sol in water, alcohol, acetone. Insol in ether. Oxidizes aldoses and ketoses, as well as other a-ketols, and is thereby reduced to a water-insoluble, deep red pigment, a triphenylformazan. Use: 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.
