- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2008-06-30 till 2009-03-13
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- thermal analysis
- Key result
- Melting / freezing pt.:
- >= 21.2 - <= 26.4 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Conclusions:
- The melting raneg for the test item 10-undecenoic acid was determined to be : 21.2-26.4 °C.
- Executive summary:
The melting point was determined for the test item 10 -undecenoic acid according to a OECD Guideline 102 study, under GLP. The thermal analysis method was applied, using Differential Scanning Calorimetry (DSC). The initial extrapolated temperature is 21.2°C and the peak temperature is 26.4 °C thus the melting range of the substance is : 21.2 -26.4°C.

The result given represents the mean value of three independant runs. The standard deviation was 0.3°C for the lower limit of the melting point temperature range, and 0.6°C for the upper limit of the melting point temperature range.
As temperatures Tei and Tp differs from more than 0.5°C, they are both reported in the results.
Melting range:
Initial extrapolated temperature: Tei = +21.2°C
Peak temperature: Tp = +26.4°C
Description of key information
The melting range was determined to be 21.2-26.4 °C at normal atmospheric pressure.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 26.4 °C
Additional information
A OECD Guideline 102 study without deviations and under GLP is available. The thermal analysis method was applied, using Differential Scanning Calorimetry (DSC). The melting range was determined to be : 21.2-26.4°C. Key value for chemical safety assessment: 26.4°C (peak temperature).
