Description of key information

Guanidine hydrochloride doesn't ignite with a hot flame, with a glowing Platinium wire or in a glowing ironcup.
Guanidine hydrochloride doesn't ignite when applied on a hot suface (360 °C) or when blown as dust (0.5 g) on a hot surface (600 °).
Guanidine hydrochloride doesn't ignite on heating in contact with air, it doesn't release flammable gases in contact with water.

Key value for chemical safety assessment

Additional information

Guanidine hydrochloride doesn't ignite

  • with a hot flame, with a glowing Platinium wire or in a glowing inron-cup
  • when applied on a hot surface (360 °C) or when blown as dust (0.5g) on a hot surface (600 °C)
  • on heating (up to 350 °C) in contact with air.

Guanidine hydrochloride (tested amount: 121 g) showed no exothermic reaction at heating on 173 °C over 92 hours.

Guanidine hydrochloride doesn't release flammable gases in contact with water.

Justification for classification or non-classification

According to testing and cited information on water solubility, Guanidine hydrochloride is not to be classified as

  • flammable solid
  • pyrophoric solid
  • self-heating substance
  • substance, which, in contact with water, emit flammable gases
