Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Remarks:
- Melting point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From May 22, 2007 to July 20, 2007
- 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
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- not specified
- Principles of method if other than guideline:
- The test substance was dried and a small amount tightly packed into a capillary tube to a height of 3 mm. Following an initial estimation of melting point, the melting point apparatus was set at approximately 10°C below the expected melting temperature (melting was observed from approximately 45°C in a preliminary test at a heating rate of 10°C/minute). The capillary tube was placed in the apparatus and heated at 1°C/minute until melting was complete. The procedure was performed in duplicate using a fresh sample on each occasion.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Remarks:
- Capillary tube in a metal block
- Specific details on test material used for the study:

- Conclusions:
- Under study conditions, the melting point of the test substance was determined to be 48 to 54°C.
- Executive summary:
A study was conducted to determine the melting point of the test substance, C14 ADBAC, according to the OECD Guideline 102 and EU Method A.1, in compliance with GLP. The study was performed as per capillary tube in a metal block method. Under study conditions, the melting point of the test substance was determined to be 48 to 54°C (Sydney 2007).
