Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Type of method:
- other: standard laboratory method
- Key result
- Melting / freezing pt.:
- < -13.86 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: other details not available
- Cold Water
- Crushed Ice

- Dry Ice
- Other (specify)
- Glass thermometer
- Thermocouple
- Thermistor
- Other (specify)
- Conclusions:
- No freezing was observed up to -13.86°C. Hence, the freezing point was inferred to be less than -13.86°C at 971.1 hPa.
- Executive summary:
The Freezing point determination of test chemical was done using crushed ice and salt. No freezing was observed up to -13.86°C. Hence, the freezing point was inferred to be less than -13.86°C at 971.1 hPa.

Description of key information
No freezing was observed up to -13.86°C. Hence, the freezing point was inferred to be less than -13.86°C at 971.1 hPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -13.86 °C
Additional information
The Freezing point determination of test chemical was done using crushed ice and salt. No freezing was observed up to -13.86°C. Hence, the freezing point was inferred to be less than -13.86°C at 971.1 hPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
