Reference
The test item had a significantly broadened melting peak with a maximum at- 75 °C, ranging from about -100 to -71 °C.
| determination | initial temperature [°C] | peak temperature [°C] | end temperature [°C] |
| Test 1 | ~ -100 | -74.2 | -70.5 |
| Test 2 | ~ -100 | -73.9 | -69.3 |
| Test 3 | ~ -100 | -75.5 | -71.8 |
| A | ~ -100 | -75.3 | -71.1 |
| B | ~ -100 | -75 .1 | -71.6 |
| mean value | ~ -100 | -75 | -71 |
The estimated accuracy is ± 1 °C.
TG/DSC-Test (non-GLP) was run up to 600 °C. An endothermic peak starting at about 150 °C with a total weight loss at about 300 °C showed the vaporization of the test item.
Description of key information
-75°C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -75 °C
Additional information
The melting point was determined according OECD TG 102. The test item had a significant broadened melting peak with a maximum at -75°C, ranging from about -100 to -71°C (BASF SE 15L00501).
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).
