- Type of method:
- other: prediction by QSAR
- Key result
- Melting / freezing pt.:
- -44.69 °C
- Remarks on result:
- other: mean of 2 QSAR predictionq
- Melting / freezing pt.:
- -60.05 °C
- Remarks on result:
- other: Adapted Joback Method
- Melting / freezing pt.:

- Remarks on result:
- other: Gold and Ogle Method
- Conclusions:
- Melting point of -44.69°C is calculated by MPBVP v1.4.3 (EPI Suite v4.11; USEPA) as mean of values of -60.05°C (adapted Joback method) and -29.33°C (Gold and Ogie method).
- Executive summary:
Melting point of -44.69°C is calculated by MPBVP v1.4.3 (EPI Suite v4.11; USEPA) as mean of values of -60.05°C (adapted Joback method) and -29.33°C (Gold and Ogie method).

Description of key information
The weight of evidence approach may apply as 2 independent sources of information are available:
A) Melting point of -97.3°C is reported in publications (Timmermans, 1927; cited by Ghysels, 1924)
B) Melting point of -44.69°C is calculated by MPBVP v1.4.3 (EPI Suite v4.11; USEPA)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -97.3 °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.
