Applicant's summary and conclusion

Conclusions:
The melting and boiling temperature of 3,4,5-TRIMETHOXYCINNAMIC ACID were determined by DSC.
The melting temperature of the test item was 127.283°C (400.4K).
Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of > 250°C (> 523K). 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.
