Description of key information

Sulphamidic acid decomposes at approx. 209 °C before boiling and thus the boiling point at atmospheric pressure cannot be determined. 

Key value for chemical safety assessment

Additional information

In public literature (peer reviewed handbooks) the substance is reported to decompose directly after melting at approx. 209 °C. Consequently, determination of the boiling point is not possible as the substance decomposes at 209 °C before boiling.
