Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 13.09.2017 - 15.09.2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Key result
- Melting / freezing pt.:
- 92.1 °C
- Atm. press.:
- 982 hPa
- Conclusions:
- Under the conditions of the study, the melting point of the test substance Solvent Blue 79 was found to be 92.1°C.
- Executive summary:
The melting point of the test substance was determined using the Capillary method. A small amount of the test item was heated in the electronic controlled sample block and the temperature around the sample was displayed. The sample was observed visually while raising the temperature.
Using a linear heating rate of 0.5°C/min the melting point of Solvent Blue 79 was found to be 92.1 ± 0.29 °C (95 % confidence interval).
