Resazurin, with the CAS number 550-82-3, is a redox indicator commonly used in microbiology and biochemistry. It is a non-toxic, fluorescent compound that appears blue in its oxidized form and turns pink upon reduction, making it useful for assessing cellular viability and metabolic activity. Resazurin is soluble in water and exhibits a pH-dependent color change, which allows for visual monitoring of biological processes. Its ability to permeate cell membranes enables it to enter living cells, where it is reduced to resorufin, a more fluorescent and pink compound. This property makes resazurin an effective tool in assays for evaluating the growth of microorganisms, as well as in various applications in drug testing and toxicity studies. Additionally, resazurin is stable under normal laboratory conditions, although it should be protected from light to prevent degradation. Overall, its ease of use and clear visual indicators make resazurin a valuable reagent in scientific research.

<p>Weakly fluorescent blue dye; indicator of mitochondrial activity. The reduction of resazurin has been ascribed to a putative reductase or diaphorase-type enzymes from the mitochondria and cytosol but also it might play a role as an intermediate electron acceptor in the electron transport chain between the final reduction of oxygen and cytochrome oxidase.</p>
