Any other information on results incl. tables

Both of the main constituents of the substance contain azo groups, which are known structural alert for explosivity. In addition, the oxygen balance value of each constituent is a greater positive than -200 (constituent 1: -86.94; constituent 2: -106.09). The DSC evaluation of the melting temperature of Yellow 98 -2 states that "the curve drifts into the exothermic region, indication decomposition". The curve shows this to be 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). Based on this 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, Yellow 98-2 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 indicating that the substance is unlikely to be explosive.
