Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
A literature search (see attached for references) gave a range of resuts for the experimental melting point. These ranged from 145.5°C to 219°C, however the 145.5°C result was considered to be inaccurate given that 14/15 studies concluded the melting point was >200°C.

The average melting point obtained from the remaining 14 studies was calculated as 215°C from the remaining studies, 13/15 summarised studies gave results withing the range 210-220°C - this has been included as representative melting point range for this substance.
