Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
auto-flammability
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Justification for type of information:
Experimental test result performed using standard test guidelines
Qualifier:
according to guideline
Guideline:
other: Lowest temperature determined at which substance vaporizes to form an ignitable mixture in air
Principles of method if other than guideline:
Lowest temperature determined at which substance vaporizes to form an ignitable mixture in air
GLP compliance:
not specified
Relative self-ignition temperature:
> 300 °C
Remarks on result:
other: disodium 3-oxo-3H-spiro[2-benzofuran-1,9'-xanthene]-3',6'-diolate did not catch fire on being exposed to air at room temperature of 27°C
Conclusions:
disodium 3-oxo-3H-spiro[2-benzofuran-1,9'-xanthene]-3',6'-diolate did not catch fire on being exposed to air at room temperature of 27°C and atmospheric pressure of 966 hPa. This indicates that disodium 3-oxo-3H-spiro[2-benzofuran-1,9'-xanthene]-3',6'-diolate is not auto-flammable Also the self ignition temperature was estimated to be greater than 300 degree celcious.
Executive summary:

disodium 3-oxo-3H-spiro[2-benzofuran-1,9'-xanthene]-3',6'-diolate did not catch fire on being exposed to air at room temperature of 27°C and atmospheric pressure of 966 hPa. This indicates that disodium 3-oxo-3H-spiro[2-benzofuran-1,9'-xanthene]-3',6'-diolate is not auto-flammable Also the self ignition temperature was estimated to be greater than 300 degree celcious.
