Tiron Usage And Synthesis
Chemical Propertieslight tan powder
UsesIn determination of trace metals.
UsesTiron is a superoxide scavenger used in the study and examination of oxide electronics. Maintains the ability to remove or destroy magnetic moments which may occur on the surface of such materials.
DefinitionChEBI: Tiron is an organic molecular entity.
Purification MethodsRecrystallise it from water [Hamaguchi et al. Anal Chim Acta 9 563 1962]. Itisan indicator colour reagent for Fe, Mn, Ti and Mo ions and complexes with Al, Cd, Co, Co, Fe (III), Mn, Pd, UO22+, VO2+ and Zn. [Beilstein 11 IV 630.]
