Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Melting range = 117.5-127.0 °C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
117.5 °C

Additional information

Two valid GLP studies, conducted according to different, but both recognized methods, were provided.

The change of state occurs within a 10°C-interval, which can be explained by the multi-constituents nature of the substance.

Both methods give consistent results for the melting range; however, the DSC method was conducted for the b.p. measurement, and no precise determination of the melting temperature was done. Therefore, the capillary method was judged more accurate, and considered as the only key study.
