Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The flammability of 1-hexyl-1H-pyrazol-4,5-diamine hemisulfate was determined accordind to the EU Method A.10 (Flammability (Solids)) and following the GLP.

Using a mold, a sample of the test material was formed into an unbroken line about 250 mm long by 20 mm wide by 10 mm high on a non-combustible, non-porous and low heat conducting surface. The flame from a Bunsen burner was applied to one end of the powder strip for two minutes.The solid test material, C6 Pyrazole Hemisulfate, did not ignite or propagate combustion.

Based on this test, 1-hexyl-1H-pyrazol-4,5-diamine hemisulfate is non-flammable.
