- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Deviations:
- no
- GLP compliance:

- Type of method:
- other: decomposition check using Mel-Temp II apparatus
- Specific details on test material used for the study:
- Substance ID: TSN101380
Purity: 98.4% - Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 170 - <= 180 °C
- Remarks on result:
- other: boiling point could not be determined due to the decomposition of the test substance upon heating
- Conclusions:
- The boiling point could not be determined due to the decomposition of the test substance upon heating. The decomposition temperature ranged from 170-180°C.
- Executive summary:
The purpose of this study was to determine the boiling point of the test substance according to the guidelines OECD 103, EU Method A.2 and EPA OPPTS 830.7220.
The test substance appeared to melt into a clear colorless liquid at approximately 40°C. Once the test substance had been heated to approximately 255°C, the melting point tube was removed. It was noticed that the test substance had changed to a yellow clear liquid indicating that it had decomposed. At no point, did the test substance appear to boil.
The boiling point could not be determined due to the decomposition of the test substance upon heating. The decomposition temperature ranged from 170-180°C.
