Iodonitrotetrazolium formazan

Description:

Iodonitrotetrazolium formazan, commonly referred to as INT formazan, is a chemical compound that is primarily used as a redox indicator in various biochemical assays. It is characterized by its vibrant red color, which results from the reduction of the iodonitrotetrazolium salt to formazan in the presence of viable cells or reducing agents. This compound is soluble in organic solvents and exhibits low solubility in water, making it suitable for applications in cell viability assays, where it helps to assess metabolic activity. INT formazan is often utilized in microbiology and cell biology to evaluate the health and proliferation of cells, as the intensity of the red color correlates with the number of viable cells. Additionally, it has applications in histochemistry and as a marker in various enzymatic reactions. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled. Overall, Iodonitrotetrazolium formazan is a valuable tool in scientific research for assessing cellular activity and viability.
