STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature in the dark - Key result
- Melting / freezing pt.:
- >= 52.4 - <= 58.7 °C
- Decomposition:
- no
- Conclusions:
- The melting temperature range of the test item has been determined to be 52.4 to 58.7 ± 0.5 °C (326 to 332 ± 0.5 K).
- Executive summary:
The melting point was investigated by differential scanning calorimetry, using a procedure designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Due to the complex nature of the melting endotherm, a range is stated in the conclusion.
The melting temperature range of the test item has been determined to be 52.4 to 58.7 ± 0.5 °C (326 to 332 ± 0.5 K).

Overall melting range : 52.4 to 58.7 ± 0.5 °C (326 to 332 ± 0.5 K)
Due to the complex nature of the melting endotherm, a range is stated in the conclusion.
Description of key information
The freezing point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 102 and EU Method A.1) and GLP. No deviations from the guidelines have been observed during the test.
The melting temperature range of the test item has been determined to be 52.4 to 58.7 ± 0.5 °C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 52.7 °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).
