Description of key information

Lide, 2008: The melting point of the test item is considered to be 18 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
18 °C

Additional information

The derived melting point is based on the literature and database queries. The most reliable value of 18.0 °C was found in Lide (2008). This information is supported by online database queries in Reaxys (2015) and Beilstein (2006). The range specified there is 18 - 20 °C. Deviating from this, a value of 7 ° C is given in Hommel (2012). In a weight of evidence approach based on all available information, the melting point of the test item is considered to be 18 °C.
