Applicant's summary and conclusion

Conclusions:
According to OECD 103 and performed via DSC (differential scanning calorimetry), the boiling point of the test item is 281.79 ± 0.04 °C (554.94 ± 0.04 K).
The sunken baseline after boiling could be a sign of decomposition and is stated as 294.85 °C (568.00 K).
