Conclusions:
The Freezing point determination of test chemical was done using crushed ice and salt. No freezing was observed up to -7.07°C. Hence, the freezing point was inferred to be less than -7.07 °C at 964.6 hPa.
Executive summary:

The Freezing point determination of test chemical was done using crushed ice and salt. No freezing was observed up to -7.07°C. Hence, the freezing point was inferred to be less than -7.07 °C at 964.6 hPa.

Description of key information

The Freezing point determination of test chemical was done using crushed ice and salt. No freezing was observed up to -7.07°C. Hence, the freezing point was inferred to be less than -7.07 °C at 964.6 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-27 °C

Additional information

The Freezing point determination of test chemical was done using crushed ice and salt. No freezing was observed up to -7.07°C. Hence, the freezing point was inferred to be less than -7.07 °C at 964.6 hPa

From reliable sources freezing point of test chemical was determine in the range between -27 to -25°C.
