INT FORMAZAN Usage And Synthesis

Uses

• Starvation-survival processes of a marine Vibrio.: This research explores the use of Iodonitrotetrazolium Violet-Formazan for studying the starvation-survival mechanisms in marine Vibrio, highlighting its application as a metabolic activity indicator under nutrient-deprived conditions, which is crucial for understanding bacterial survival strategies in natural aquatic environments (Amy et al., 1983).

Purification Methods

Dissolve it in boiling dioxane (20g in 300mL), add H2O (100mL) slowly, cool, filter and dry it in vacuo at 100o. Its solubility in CHCl3 is ~1%. [UV: Fox & Atkinson J Am Chem Soc 72 3629 1950, Beilstein 26 III/IV 1776.]
