- Adequacy of study:
- key study
- Study period:
- 4 Sept 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study

- thermal analysis
- Specific details on test material used for the study:
- Sample 1
Name: CETATS
Batch no: 99M1061L
Date of manufacture: 29/3/2012
Sample Purity: 99.5%
Date of analysis: 21/12/2016
Sample 2
Name: CETATS
Batch no: 99D1097T
Date of manufacture: 4/5/2016
Sample Purity: <99.5%
Date of analysis: 21/12/2016
Sample 3
Name: CETATS
Batch no: 99D1099T
Date of manufacture: 9/5/2012
Sample Purity: <100.1%
Date of analysis: 15/2/2016 - Remarks on result:
- not determinable
- Remarks:
- CETATS is a solid at ambient temperatures but its melting point could not be determined. CETATS exhibits two small endotherms in the 115-125 C region during differential thermal analysis. It could not be determined if these events were due to melting or solid phase transitions or both. CETATS decomposes at temperatures above 200 C. Results from 3 samples were found to be 209.7 C, 211.3 C, and 201.9 C.
- Conclusions:
- CETATS is a solid at ambient temperatures but its melting point could not be determined.
CETATS exhibits two small endotherms in the 115-125 C region during differential thermal analysis. It could not be determined if these events were due to melting or solid phase transitions or both.
CETATS decomposes at temperatures above 200 C. Results from 3 samples were found to be 209.7 C, 211.3 C, and 201.9 C.
