Description
Colorless needle crystals that yellow when exposed to light. Triphenyltetrazolium chloride (TTC) is primarily used as an analytical reagent for the detection of reducing sugars in plant and animal tissues. The colorless TTC reacts with sugars to become a deep red, water-insoluble compound (triphenylformazan). Reducing agents (i.e. borohydride, bleaching powder, chloramine T) give a positive red result.
Synonyms and Related Terms
TTC; TPTZ; red tetrazolium; tetrazolium chloride; 2,3,5-triphenyl-2H-tetrazolium chloride; Vitastain; tetrazole red
Other Properties
Soluble in ethanol, water, acetone. Insoluble in ether.
