| | Potassium nitrosodisulfonate Usage And Synthesis |
| Chemical Properties | orange moist powder and chunks | | Uses | Is a reagent for oxidation of multiple phenols and anilines to quinones | | Uses | Reagent for the oxidation of anilines and phenols to quinones. EPR standard. | | Uses | Useful reagent for the oxidation of a variety of phenols and anilines to quinones. | | Uses | Dipotassium Nitrosodisulfonate is a valuable radical molecule that performs oxadations on various chemical compounds including phenols, napthols, amines, indoles . It is an invaluable tool in EPR (electron paramagnetic studies) and has seen use in the synthesis of antitumor agents. | | reaction suitability | reagent type: oxidant | | Purification Methods | It forms yellow needles (dimeric) which dissolve in H2O to give the violet monomeric free radical. It is purified by dissolving (~12g) in 2M KOH (600mL) at 45o, filtering the blue solution and keeping it in a refrigerator overnight. The golden yellow crystals (10g) are filtered off, washed with MeOH (3x), then Et2O and stored in a glass container in a vacuum over KOH. It is stable indefinitely when dry.
