Applicant's summary and conclusion

Conclusions:
The melting and boiling temperature of V134434 were determined by DSC. The melting temperature of the test item was 89.3°C (362.4K).
Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of > 89.3°C (> 362.4K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
