Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- The batch of Disperse Brown 27 (4852-1501) tested was a brown powder with a purity of 99.7 %
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 225 ca. °C
- Conclusions:
- No boiling point, samples degraded at a temperature of >225C
- Executive summary:
Reaction and/or decomposition of Disperse Brown 27 was observed during DSC experiments at temperatures of > 225°C (> 498K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
Reference
No boiling point, samples degraded at a temperature of >225°C
Description of key information
