Any other information on results incl. tables

Both of the main constituents of the substance contain an azo group, which is a known structural alert for explosivity. In addition, the oxygen balance value of each constituent is a greater positive than -200 (constituent 1: -71.19; constituent 2: -83.98). The DSC evaluation of the melting temperature of Red VP2298 states that "the curve drifts into the exothermic region" and that "there are indications of decomposition above 220° C". This indicates that exothermic decomposition occurs below 500° C, which is part of the criteria for judging the substance as non-explosive. In addition, the substance is not highly flammable (EU method A.10) and it is not auto-flammable up to 400° C (EU Method A.16). Based on these data, the substance is unlikely to be explosive.

Applicant's summary and conclusion

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
In conclusion, on the basis of structure and oxygen balance, Red VP2298 is considered to have the potential to be explosive, however the substance has an onset of exothermic decomposition below 500 °C and it is not highly flammable or auto-flammable up to 400 °C indicating that the substance is unlikely to be explosive.
