Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Remarks:
- No boiling point measured because of decomposition of the test substance
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- Determination of the melting and boiling point
according to OECD 102 / 103 resp. EU A.1 / A2 - Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 158.81 °C
- Remarks on result:
- not determinable
- Conclusions:
- No melting or boiling point of Blendazol Red could be determined via DSC (differential scanning calorimetry) under these circumstances, because of decomposition of the test substance.
In all runs small endothermic and exothermic were detected.
Referring to the pre-test, beginning decomposition was observed at 197 °C indicated by colour change. The bloated crucible after the DSC measurements and the remained black residue confirm the decomposition.
Therefore, beginning decomposition should be stated as:
158.81 °C (431.96 K) - Executive summary:
The melting and boiling point of Blendazol Red was determined according to OECD 102/103 resp. EU A1/ A
No melting or boiling point of Blendazol Red could be determined via DSC (differential scanning calorimetry) under these circumstances, because of decomposition of the test substance.
