Application

Tetrazolium blue chloride (BTC) is a colorless tetrazolium compound that upon reduction forms a colored diformazan. The reactivity has been applied to the analysis of reducing compounds including the nanomolar detection of reducing sugars and carbidopa and methyldopa. BTC has been used for histological staining of mouse coronal brain sections and rat brain sections. In combination with 4-nitrocatechol, tetrazolium blue chloride forms a ternary complex with molybdenum(VI) for extraction and spectrophotometric determination of molybdenum. It has also been used to stain Francisella tularensis cells for tularemic microagglutination test.
