Constituent 1
- Specific details on test material used for the study:
- -Storage conditions
The test sample was sealed with nitrogen gas and stored with silica gel in a dark storage place at room temperature.
-Test item identification and stability under storage conditions
The infrared (IR) spectrum of the test item measured at this test facility was confirmed to be identical to that provided by the sponsor.
In addition, the IR spectrum of the test item after the completion of the experiment was the same as that before the start of the experiment, and it indicated that the test item was stable under the storage conditions.
Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- > 113 - < 122 °C
- Remarks on result:
- other: Mean of two replicates
Any other information on results incl. tables
Number of repetition | Measured values (ºC) | |
Beginning of melting | Final stage of melting | |
1 | 113.0 | 122.0 |
2 | 113.0 | 122.0 |
Average | 113.0 | 122.0 |
The color change of the test item was not observed in the melting range of test item. Therefore, it is considered that the test item is stable in the melting range.
