- Atm. press.:
- 101.325 kPa
- Decomposition:
- no
- Conclusions:
- The boiling range of undec-10-enoic acid is reported to be : 286.05-293.75 °C.
- Executive summary:
The boiling point of test item undec-10-enoic acid was determined in a OECD Guideline 103 study, under GLP. The differential thermal analysis method was applied. The initial extrapolated temperature is 286.05°C
and the peak temperature is 293.75°C thus the boiling range of the substance is: 286.05 -293.75°C.

Description of key information
The boiling range was determined to be 286.05-293.75 °C at normal atmospheric pressure.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 293.75 °C
Additional information
A OECD Guideline 103 study without deviations and under GLP is available. The differential thermal analysis method was applied. The initial extrapolated temperature is 286.05°C and the peak temperature is 293.75°C thus the boiling range is 286.05 -293.75°C. Key value for chemical safety assessment : 293.75°C (key temperature).
