Synonyms: 5-Cyano-2,3-bis(4-methylphenyl)-2H-tetrazolium chloride, CTC
5-Cyano-2,3-di-(p-tolyl)tetrazolium chloride (CTC) is a widely used and accepted dye in environmental and ecological studies. The redox dye CTC is a good vital stain for estimating aerobic bacteria with high metabolic activity due to their ability to reduce CTC to the fluorescent product.
C 5047 (OTTO) 5-Cyano-2,3-di-(p-tolyl)tetrazolium chloride, ≥85% (HPLC) Cas 90217-02-0 - used to measure the redox activity of tumor cells. It has also been employed for direct epifluorescent microscopic enumeration of respiring bacteria in food samples and environmental samples, especially water samples.
