- Conclusions:
- L-TEE was showned to melt in the range of 54°C to 58°C.
- Executive summary:
The melting point of L-TEE was determined by Differential scanning calorimetry (DSC) in accordance to EU Method A.1 (Melting / Freezing Temperature).
There was good agreement between the result for the preliminary and definitive melting tests, and the mean melting onset and endset temperatures were 54.04°C and 58.01 °C, respectively.
L-TEE was found to be a compound which undergoes conventional melting from 54.0°C to 58.0°C.
