- key study
- Study period:
- from 1999-04-16 to 2000-01-31
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 92/69/EEC
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- capillary method
- Specific details on test material used for the study:
- Batch No.: 13111BR
Purity: 99.3 % - Key result
- Melting / freezing pt.:
- 77.1 °C
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The mean value out of all measurements of the melting point of the test item was determined to be 77.1 °C (350.3 K).
- Executive summary:
The melting temperature of the test item was determined according to EPA-Guideline 830.7200 and EEC-Guideline 92/69/EEC A.1, capillary method. Therefore, samples of the test substance were filled into melting point capillaries. These samples were exposed to a temperature/time-gradient while the intensity of the light beam which was directed trough the sample was recorded. The test was performed three times. The mean value out of all measurements of the melting point of the test item was determined to be 77.1 °C (350.3 K).
