Conclusions:
The Freezing point determination of test chemical was done using crushed ice + salt. No freezing was observed up to -14.08°C. Hence, the freezing point was inferred to be less than -14.08 °C at pressure 973.5 hPa.
Executive summary:

The Freezing point determination of test chemical was done using crushed ice + salt. No freezing was observed up to -14.08°C. Hence, the freezing point was inferred to be less than -14.08 °C at pressure 973.5 hPa.

Description of key information

The Freezing point determination of test chemical was done using crushed ice + salt. No freezing was observed up to -14.08°C. Hence, the freezing point was inferred to be less than -14.08 °C at pressure 973.5 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-14.08 °C

Additional information

The Freezing point determination of test chemical was done using crushed ice + salt. No freezing was observed up to -14.08°C. Hence, the freezing point was inferred to be less than -14.08 °C at pressure 973.5 hPa.

From other reliable sources & authoritative databases freezing point of test chemical was determine to be -10 °C & in the range between -63 to -10 °C.
