Application
Potassium nitrosodisulfonate can be used as an oxidizing reagent for the oxidation of:
- Aromatic amines to their corresponding quinones.
- Hydroethidine to 2-hydroxyethidium.
- Tyrosine to o-quinones.
General description
Potassium nitrosodisulfonate is an oxidizing reagent that can be used to convert phenols, naphthols, and anilines to quinones, benzylic alcohols to aldehydes or ketones, and amino acids to α-keto acids. It can also be used for the preparation of heterocyclic quinones and oxidative aromatization.

Nitroxyldisulfonate [Fremy's salt; (KSO3)2NO.] and bisulfite (NaHSO3) have abolished periodic acid (H5IO6)-induced blastogenesis of human peripheral blood lymphocytes (HPBL), but only inhibited the blastogenic response of H5IO6-oxidized rat and mouse lymphocytes, as determined by the rates of nucleic acids synthesis

Bisphenol A was oxidized to monoquinone and bisquinone derivatives by Fremy's salt, a radical oxidant, though salcomine and alkali did not catalyze the oxidation by molecular oxygen. Bisphenol A, bisphenol B, and 3,4'-(1-methylethylidene)bisphenol were converted to their monoquinone derivatives in

The effectiveness of dynamic nuclear polarization (DNP) as a tool to enhance the sensitivity of liquid state NMR critically depends on the choice of the optimal polarizer molecule. In this study the performance of (15)N labelled Frémy's salt as a
