Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Experimental test result performed using standard OECD test guidelines.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- no
- Type of method:
- other: Capillary/metal block
- Key result
- Melting / freezing pt.:
- 105.1 - 108.6 °C
- Atm. press.:
- 976.1 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The melting point determination of test chemical was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean melting temperature range was determined to be 105.1-108.6°C at 976.1hPa.
- Executive summary:
The melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The mean melting temperature range was determined to be 105.1-108.6°C at 976.1 hPa.

Description of key information
The melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The mean melting temperature range was determined to be 105.1-108.6°C at 976.1 hPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 105.1 °C
Additional information
The melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The mean melting temperature range was determined to be 105.1-108.6°C at 976.1 hPa.
Based on the data from other supporting study from various reliable sources such as handbooks and authoritative database, the melting point of test chemical was determined to be 109 °C which is in the range of key study value. Thus, for the purpose of chemical safety assessment we will consider the key study value which is reported as 105.1-108.6°C at 976.1 hPa.
