Any other information on results incl. tables

The extrapolated onset of the peak between 200°C and 325°C obtained in the first experiment was 285.036°C. The similar value found in an earlier experiment (results were not used due to a lower sample amount used) demonstrated that boiling of the test item was the reason for the endothermic effect. After the experiment it was observed that the test item was evaporated from the sample container.

A further experiment was performed to determine the boiling temperature of the test item. Similar results were obtained. The extrapolated onset of the evaporation

peak was 285.792°C. After the experiment it was observed that the test item was evaporated from the sample container.

The boiling temperature was determined as the average boiling temperature obtained from two experiments (285.036°C; 285.792°C) and equals 285.4°C (558.6K).

Applicant's summary and conclusion

Conclusions:
The boiling temperature of JNJ-17337268-AAA (T001597) was determined at 285.4°C (558.6K) by using DSC.
The atmospheric pressure was 1020 ± 3 hPa.
