Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

no guideline followed
Principles of method if other than guideline:
Experimental techniques are available for the classification of a substance or preparation as explosive. These are described in EC Test A14. However, according to the OECD testing methods publication, test A14 need not to be carried out when examination of the structural formula establishes beyond reasonable doubt that the substance has no explosive properties (i.e. it is not capable of rapid gas or heat release).
GLP compliance:
other: Explosive under influence of flame
Remarks on result:
negative (not further specified)

Assessment of Explosive Properties of the test substance:

Examination of the structural formula indicates:

• There are no chemical groups associated with explosive properties.

• The oxygen is not bound in energetic functional groups – it is bound in CO groups which do not possess explosive behaviour.

• Thermal stability analysis has been conducted on the sample using Differential Scanning Calorimetry (DSC). Two exothermic events were observed. The first from 128.8°C (-22.0 J.g-1) and the second from 239.3°C (-433.5 J.g-1). The total heat of decomposition was found to be < 500 J/g).

Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties. There are no elements of the screening procedure which begin to suggest that explosive properties may be exhibited by the substance. The conduct of the A14 tests is therefore not considered appropriate.

Differential Scanning Calorimetry (DSC)

A sample of the test substance was charged to a gold (high pressure) DSC crucible which was then sealted and placed in the furnace. The sample was then ramped from 25°C to 500°C at 4 K. min-1.

Test results

The sample was observed to undergo an exothermic event from 128.8°C which had a heat of decomposition of -22.0 J.g-1, a second exothermic event was observed at 239.3°C which had a heat of decomposition of -433.5 J.g-1. No further significant events were noted up to 500°C.

Interpretation of results:
GHS criteria not met
Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties.

Description of key information

In accordance with column 2 of REACH Annex VII the explosive properties study does not need to be conducted as there are no chemical groups associated with explosive properties present in the molecule.  The substance contains none of the functional groups quoted in “Recommendations on the transport of dangerous goods – Manual of Tests and Criteria” 4th revised edition, Appendix 6, table A6.1, which may indicate explosive properties.   Therefore, it can be concluded that this substance is not explosive in the senses of EC A14 and the UN Manual of Tests and Criteria.
