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
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Remarks:
- The study was conducted according to the test guidelines in effect at the time of study conduct.
- GLP compliance:
- yes
- Type of method:
- capillary method
- Melting / freezing pt.:
- 244 - 248 °C
- Conclusions:
- The melting range of the test substance has been determined as 244.0-248.0°C.
- Executive summary:
The melting point/range of the test substance was determined using the metal block method according to EEC Directive 67/548, Annex V, A1 as published in 84/449/EEC. Two tests were run. The results were 244.5 -247.5ºC and 243.0 -248.0ºC for Tests 1 and 2, respectively. The test substance began to darken slowly at 170ºC (test 1) and 165ºC (test 2). The sample completely melted at 247.5ºC (test 1) and 248ºC (test 2) to produce a brown liquid which solidified, on cooling, to an opaque light-brown solid.
