Chemical name: 2-Ethylhexyl 2-([1,1'-biphenyl]-4-ylcarbonyl)benzoate
CAS number: 75005-95-7
EC Number: 278-051-5
Molecular formula: C28H30O3
Molecular weight: 414.22 - Auto-ignition temperature:
- 420 °C
- Atm. press.:
- > 1 019 - < 1 024 hPa
- Conclusions:
- Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of the test item.

The atmospheric pressure was 1019 and 1024 hPa. - Executive summary:
In this guideline (EU A.15) study, conducted with GLP certification, the test item is auto-ignitable with an auto-ignition temperature of 420°C. at 1013 hPa.
Reference
Preliminary Test
The estimated auto-ignition temperature was 450°C.
Main Study
The results of the main study on the determination of the auto-ignition temperature of the test item are given in Table 7.
Ignition of the test item within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 20°C. According to the guidelines, no further testing was required.
The lowest temperature at which ignition of the test item occurred was 424°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 420°C.
