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:
- From December 1 to 12, 2008
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised with its purity. Validation applies, with minor restrictions due to heating rate.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- yes
- Remarks:
- heating rate
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- yes
- Remarks:
- heating rate
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 53736: Method for the Determination of Melting Point
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Swiss GLP compliance programme (inspected on November 15 and 16, 2006 / signed on March 29, 2007)
- Type of method:
- capillary method
- Specific details on test material used for the study:
- Storage condition of test material: Refrigerator (between 0 and 10 °C under nitrogen)
- Key result
- Melting / freezing pt.:
- 35 °C
- Atm. press.:
- 96.7 kPa
- Executive summary:
The melting point of the test substance was determined under GLP according to EU Method A.1, OECD Guideline 102 and DIN 53736 (method for the determination of melting point) using capillary method. Two main runs were performed, and the mean final temperature was retained.
The melting temperature of test substance has been determined to be 35 ± 1 °C (308 ± 1 K) at 96.7 kPa.
Reference
Preliminary test: 307.6 K (34.6 °C) at 96.7 kPa
Determination 1: 307.9 K (34.9 °C) at 96.7 kPa
Determination 2: 307.8 K( 34.8 °C) at 96.7 kPa
Description of key information
Low melting solid.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 35 °C
Additional information
A reliable experimental study, conducted according to a recognized OECD/EU method and under GLP, is available. Despite minor restrictions due to technical inaccuracy, it is considered as a key study, and the result is retained as key data.
