Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Based on the structure of the molecule and taking into account the provisions laid down in Regulation (EC) 1227/2008 (CLP), the test item does not have to be classified with respect to explosiveness. In accordance with column 2 adaptation statement of Annex VII Regulation (EC) No 1907/2006 (REACH), the determination of the explosive properties (as required in section 7.11 of Annex VII) was waived based on a structural assessment of the substance. The test item does not contain any functional groups quoted in ‘Manual of Tests and Criteria’ (sixth revised edition, appendix 6, and table A 6.1) or Bretherick’s – Handbook (7th Edition, Volume 2, p 128 ff) which may indicate explosive properties. Therefore, it can be concluded by expert judgment that this substance is not explosive.
This assessment is supported by the results of a Differential Scanning Calorimetry (BASF SE, 2017). The test item sample (16.4 mg) was subject to a controlled temperature program in a closed vessel (closed high pressure cell made of V4A). From the temperature difference between the sample and the inert substance (empty container), which was in thermal contact with the sample, the heat flow from or to the sample was measured as a function of the furnace temperature (heating rate: 2.5 °C/min; temperature range: from 30 °C to 500 °C). In a first exothermic reaction, >30 J/g was released at an onset temperature of 430 °C and a peak temperature of 476 °C. Thus, the released energy was far below 500 J/g and, furthermore, the reaction started at an temperature below 500 °C. Hence, the tests on explosiveness do not have to be conducted in accordance with Regulation (EC) 1907/2006 (REACH), Annex VII, section 7.11, column 2.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on reliable data (BASF SE, 2017), the chemical structure and taking into account the provisions laid down in Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EC) No 2017/776, the substance is not considered to be classified for explosive properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
