Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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.
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.
