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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
