ca 205° dec.
Slightly soluble in water, dimethyl fluoride and methanol. Insoluble in hydrocarbons.


Amidosulfonic acid is widely utilized as a green catalyst for the preparation of amide from ketoxime. It finds an application as a titrant in the determination of the burette injection volume and chemical calibration factor. It is an efficient catalyst in the synthesis of polyhydroquinoline derivatives by Hantzsch condensation reaction, deazaoxaflavin, fatty acid methyl and ethyl esters and in the isolation of 5-hydroxymethylfurfural (HMF) from bamboo fiber. It is involved in the determination of silicates in water samples. It acts as a neutralizing agent during the determination of paracetamol by Glynn and Kendal colorimetric method.


Incompatible with chlorine compounds, nitrates, carbonates, strong oxidizing agents and strong bases.


Widely used to destroy excess HNO2 in diazotization reactions. Effective catalyst for acetylation of alcohols and phenols with acetic anhydride at room temperature: Synth. Commun., 28, 3173 (1998). Solvent-free tetrahydropyranylation of alcohols has been accomplished under mild conditions: Synth. Commun., 33, 3929 (2003). Catalyzes the addition-esterification of aliphatic carboxylic acids with cyclic olefins: Catal. Lett., 96, 71 (2004). For a brief feature on uses in synthesis, see: Synlett, 1342 (2005).
