Description of key information

non explosive (EU A.14, based on assessment of structural features and oxygen balance)

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The molecular structure of the substance 2-hexyldecanoic acid [4-(6-tert-butyl-7-chloro-1H-pyrazolo[1,5-b][1,2,4]triazol-2-yl)phenylcarbamoyl]methylester (UM-235) does not contain any chemically instable or highly energetic groups that might lead to an explosion.

 

Using C32H48ClN5O3 as molecular formula and 586.22 g/mol as molecular weight for UM-235, the oxygen balance for the test substance was calculated to be -232 %. This value is outside the region where there may be a potential for explodability.

 

In conclusion, UM-235 is not explosive.

Justification for classification or non-classification

The available data on explosive properties 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: Based on assessment of the chemical structure and oxygen balance, the substance is not explosive.
