Description of key information

Aminoguanidinium hydrogen carbonate melted when approached by the ignition flame. Aminoguanidinium hydrogen carbonate did not burn down or burn up.
Pyrophoric properties:
Experience in production or handling; aminoguanidinium hydrogen carbonate is known to be stable at room temperature. Aminoguanidinium hydrogen carbonate has no pyrophoric properties.
Contact with water:
Aminoguanidinium hydrogen carbonate does not emit flammable gases in contact with water. The structural formulas of the compounds of the mixture contain none of the functional groups quoted in Manual of Tests and Criteria, appendix 6, article 5.3).

Key value for chemical safety assessment

non flammable

Additional information

Justification for classification or non-classification

Aminoguanidinium hydrogen carbonate not yet classified in the Annex I of Directive 67/548/EEC. According to the information summarized below, no classification on flammability is needed:

- As liquid, no flash point up to 249 °C;

- As liquid, boiling point is higher than 300 °C;

- No pyrophoric property, based on experience from production and handling;

- It does not ignite spontaneously with water and does not liberate flammable gases in hazardous amounts in contact with water.

Based on the data summarized above, aminoguanidinium hydrogen carbonate is also not flammable according to GHS (Regulation EC 1272/2008).
