Description of key information

Freezing point of test chemical was determined to be  -5.63 degree celcius.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-5.63 °C

Additional information

From experimental report, Freezing point of test chemical was determined to be  -5.63 degree celcius.

Based on available data from reliable sources such as authoritative database and handbook ,the freezing point of test chemical was determined to be -2 degree C.

Thus the freezing point of test chemical was determined to be -5.63 degree celcius.
