Description of key information

The melting range of the substance is determined to 127.5 to 129.6 °C.

Key value for chemical safety assessment

Additional information

The melting range of the substance is derived from a weight-of-evidence approach of an experimental study and three secondary sources. The values derived from these sources fit together and differ only slightly. Whereas the experimental study and one of the secondary sources agreed in the statement of a melting range instead of a fix melting point both other sources state the lower respective the upper end of the melting range. The weight of evidence approach is therefore considered as valid. The experimental result is considered as the most valid source regarding secondary data about the substance like e.g. purity. The experimental study is therefore chosen as key value for the chemical safety assessment.
