For the boiling point, six assays were performed.

For the boiling point, the two first assays were taking into account.

The other assays were done for confirmation. The quantities of test item weighed were too small for the assays No. 3 to 5. Boiling point was recorded at 38.1 °C and 38.5 °C for the assays No. 3 and 4 respectively. For the assay No. 5, no significative endothermic peak was recorded.

In these assays, Heating phase was from 25 °C to 150 °C at 10 °C/min ( Isotherm at 25 °C for 5 min) and the Cooling phase was from 150 °C to 25 °C at 50 °C/min (Isotherm at 25 °C for 10 min)

The mean corrected boiling point of the test item was 47.7 °C ± 0.5 °C. Correction was carried out using the Sidney Young equation.

Conclusions:

The mean corrected boiling point of the test item was 47.7 °C ± 0.5 °C.

Executive summary:

The boiling point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 103 and EU Method A.2) and the test was GLP compliant.

The boiling point has been obtained based on two measurements performed at 986 hPa.

The mean corrected boiling point of the test item was 47.7 °C ± 0.5 °C.

Description of key information

One reliable study (Klimisch 1) is available for this endpoint.

The boiling point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 103 and EU Method A.2). the test was GLP compliant and no deviation from the guidelines was observed during the test.

The boiling point has been obtained based on two measurements performed at 986 hPa.

The mean corrected boiling point of the test item was 47.7 °C ± 0.5 °C.

Key value for chemical safety assessment
