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:
- 1999-02-21 to 1999-08-23
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- adopted July 27, 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- December 1992
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 240 °C
- Sublimation:
- no
- Conclusions:
- The test substance (EC: 433-100-1) started to decompose or react at about 240 °C (513 K) using a heating rate of 10 K/min.
- Executive summary:
The determination of the melting point / melting range of the test substance (EC: 433-100-1) was performed in accordance with OECD guideline No. 102 and EU method A.1. The determination of the melting point / melting range was performed in duplicate by visual judgment using the capillary method. Two independent aliquots of the test substance (EC: 433-100-1) were heated each in a glass capillary in the melting point from room temperature with a heating rate of 10 K/min. In the preliminary test, the test substance (EC: 433-100-1) was started changing the colour from white to brown at a temperature of about 240 °C (513 K). This observation could be deduced from a reaction or decomposition of the test substance. After cooling down, a dark residue remained. No further experiments were performed because no phase transition of the test substance (EC: 433-100-1) was observed up to the decomposition or degradation of the test substance.
