Description
2,3,5-Triphenyltetrazolium chloride, min. 98 %, p.a., Molar mass (M) 334,79 g/mol, Storage temp. +4 °C, CAS No. 298-96-4, EC No. 206-071-6, Empirical formula C19H15ClN4
Used in biochemistry to measure the activity of dehydrogenases and in vital staining to detect living cells through the reduction of tetrazolium to formazan via the dehydrogenases of the respiratory chain. Triphenyltetrazolium chloride can be used to measure the bacterial content of liquids in food analysis and/or to determine seed vitality. In microbiology it is used to distinguish between coliform and noncoliform bacteria, whereas in thin layer chromatography it is ideal as a spray reagent on reducing sugar, corticosteroids and other reducing agents.
