Chemical Properties
orange moist powder and chunks
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.
Uses
Useful reagent for the oxidation of a variety of phenols and anilines to quinones.
Uses
Reagent for the oxidation of anilines and phenols to quinones. EPR standard.
Uses
Is a reagent for oxidation of multiple phenols and anilines to quinones
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.
