Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The substance Reaction mass of 2-(3,4-dimethyl-1H-pyrazol-1-yl)butanedioic acid and 2-(4,5-dimethyl-1H-pyrazol-1-yl)butanedioic acid is non-combustible on the basis of the test performed according to UN Test Procedure N.1 (33.2.1.4.1). Based on experience in handling and use and the chemical structure, flammability in contact with water and pyrophoric properties are not to be expected.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification:

No propagation of burning in a test performed according to UN Test Procedure N.1 (33.2.1.4.1).

Based on experience in handling and use and the chemical structure, flammability in contact with water and pyrophoric properties are not expected.
