- experimental study
- Adequacy of study:
- key study
- Study period:
- November 03, 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- not specified
- GLP compliance:
- yes
- Type of method:
- capillary method
- Key result
- Melting / freezing pt.:
- > 186 °C
- Atm. press.:
- ca. 101 325 Pa
- Decomposition:
- no
- Remarks on result:
- other: A Meniscus was formed at 205°C but some solids still remained and didn’t melt under 300°C. Therefore, the melting point of the test substance was considered to range from 186 to >300°C.
- Conclusions:
- Under the study conditions, the melting point temperature of the test substance was determined to be 186- >300°C.
- Executive summary:
A study was conducted to determine the melting point of the test substance, using a capillary method, according to OECD Guidleline 102, in compliance with GLP. A meniscus was formed at 205°C but some solids still remained and didn’t melt under 300°C. Under study conditions, the melting point temperature of the test substance was determined to be 186- >300°C (Scymaris, 2018).

Description of key information
The melting point of the test substance was determined using the capillary method, according to OECD Guideline 102 (Scymaris, 2018).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 186 °C
Additional information
melting point range: 186 - >300°C; as some solids still remained and didn’t melt under 300°C
