Any other information on results incl. tables

Four assays were performed during the test and two of them complied the accuracy criterion. Only these assays were taken into account for the determination of the boiling point.

The observed boiling point of the first assay was 173.5°C.The boiling point corrected to the atmospheric pressure was 174.1 °C.

The observed boiling point of the second assay was 173.0°C.The boiling point corrected to the atmospheric pressure was 173.7 °C.

The mean corrected boiling point of the test item was 173.9 °C ± 0.5 °C.

Applicant's summary and conclusion

Conclusions:
The mean corrected boiling point of the test item was 173.9°C ± 0.5°C.
Executive summary:

The objective of the study (Deitraces, 2014) is to determine the boiling point that corresponding at the temperature at which the vapour pressure of the liquid is equal to 101.325 kPa, the normal atmospheric pressure. The test item is heated under nitrogen at the atmospheric pressure using the Differential Scanning Calorimetry method (DSC), according to the OECD 103 guideline and under GLP conditions.

The mean corrected boiling point of the test item was 173.9°C ± 0.5°C.
