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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Type of method:
- capillary method
- Melting / freezing pt.:
- >= 52.8 - <= 57 °C
- Remarks on result:
- other: atmospheric pressure is reported
- Conclusions:
- A melting range of 53 - 57 °C is determined for the test substance at atmospheric pressure.
- Executive summary:
A study was conducted to determine the melting point of the test substance according to EU method A.1. A small amount of the finely ground substance (dried for 24 h in an exsiccator) is placed in a capillary tube and packed tightly. The tube is heated, together with a thermometer in an oil bath, and the temperature rise is adjusted to less than about 1 K/min during the actual melting (starting temperature 33 °C).
A melting range of 52.8 - 57 °C is determined for the test substance at atmospheric pressure.

Description of key information
A study was conducted to determine the melting point of the test substance according to EU method A.1. A small amount of the finely ground substance (dried for 24 h in an exsiccator) is placed in a capillary tube and packed tightly. The tube is heated, together with a thermometer in an oil bath, and the temperature rise is adjusted to less than about 1 K/min during the actual melting (starting temperature 33 °C).
A melting range of 52.8 - 57.0 °C is determined for the test substance at atmospheric pressure.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 52.8 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
