Remarks on result:

Remarks:
Y-15099 is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. Item 2 (oxygen balance) is not considered relevant for this substance as the substance is not adequately characterised by taking into account carbon, hydrogen and oxygen only.

STATEMENT

The explosive properties of Y-15099 were estimated based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3td edition, 1999) where a Set of criteria is compiled to identify materials being potential explosives.

 

1. Reactive Groups:

The appraisal of the molecular structure indicates no risk of rapid decomposition. Y-15099 does not contain any of the structural features mentioned in the UN Recommendations. The occurrence of other chemical groups associated with explosive properties as described in the literature (L. Bretherik: “Handbook of Reactive Chemical Hazards“, London, Butterworth, 1979) was also considered. No such groups were present.

 

2. Oxygen Balance:

The oxygen balance is not considered relevant for the evaluation of the explosive properties of this substance as it is not adequately characterised by taking into account carbon, hydrogen and oxygen only and omitting silicon and sulphur.

 

3. Calorimetric Tests

The exothermic decomposition energy was determined using Differential Scanning Calorimetry in a closed, gold plated high pressure vessel (DSC). One very small exothermic peak was detected. The onset point was at about 225 °C. The decomposition energy (¿ HDecdetermined between room temperature and 500 °C) was found to be about 23 J/g thus being far below the UN limit of 500 J/g.

Conclusion

Based on items 1 and 3 as outlined above, Y-15099 is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. Item 2 (oxygen balance) is not considered relevant for this substance as the substance is not adequately characterised by taking into account carbon, hydrogen and oxygen only.

Thus it can be concluded beyond a reasonable doubt, that Y-15099 is not a potential explosive and does not have a potential for rapid energy release. Nevertheless, this judgement is in respect to classification; it does not necessarily mean that any processing hazards can be discounted.

Interpretation of results:
GHS criteria not met
Conclusions:
Not explosive
Executive summary:

Based on item "Reactive Groups" and "Calorimetric Tests", Y-15099 is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. Item "oxygen balance" is not considered relevant for this substance as the substance is not adequately characterised by taking into account carbon, hydrogen and oxygen only.

Thus it can be concluded beyond a reasonable doubt, that Y-15099 is not a potential explosive and does not have a potential for rapid energy release. Nevertheless, this judgement is in respect to classification; it does not necessarily mean that any processing hazards can be discounted.

Description of key information

non explosive

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The substance does not contain chemical groups which are associated with explosive properties and the exothermic decomposition energy was found to be about 23 J/g thus being far below the UN limit of 500 J/g.

Justification for classification or non-classification

No classification, the substance is non explosive.

 

Justification: There are no chemical groups associated with explosive properties present in the molecule

and the exothermic decomposition energy was found to be about 23 J/g thus being far below the UN limit of 500 J/g.
