Melting point / freezing point
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:
- The study was conducted on 24 February 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- not specified
- GLP compliance:
- not specified
- Remarks:
- Study was not conducted under a specific Good Laboratory Practices (GLP) program, this study was conducted following the principles of GLP by experienced and trained personnel using calibrated standards and instrumentation. Relevant SOPs were followed.
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Lot/Batch number: 1004R18708
- Key result
- Melting / freezing pt.:
- > 395 - < 396 K
- Conclusions:
- Two sets of measurements were carried out for RD14156 and results are shown in Table 2. The DSC data presented in Appendix I indicates one strong endothermal event at 396K. The capillary measurement showed a melting point at 394 K. The results are in agreement with each other in view of the estimated accuracy, and a melting point average is taken at 395K.
- Executive summary:
The material under test was analyzed per guidelines set forth in OECD 102. A first set of determinations was carried out by Differential Scanning Calorimetry, using a TA instruments DSC2010 Calorimeter. A second set of determinations was carried out using an Electrothermal IA 9000 capillary melting point apparatus. RD14156 has a melting point of 395K.
