Description of key information

A) Flammability: not flammable solid
Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate did not burn down or burn up when tested according to UN N.1.
B) Contact with water: does not emit flammable gases in contact with water
Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate did not ignite spontaneously with water and did not liberate gases in hazardous amounts when tested according to EC Test Procedure A 12 (UN N.5).
C) Pyrophoric properties: no pyrophoric properties
Pyrophoric properties are determined following the methods N.2 (UN-Manual of testing) or A.13 (EU-method). However, in accordance with section 1 of REACH Annex XI, a study does not need to be conducted as it is scientifically unjustified. Based on experience during handling and use, no pyrophoric properties were observed; substance is known to be stable at room temperature.

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is not flammable, it has no pyrophoric properties, and no flammability in contact with water; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008).
