Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
melting point/freezing point
Type of information:
other: Secondary literature
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Remarks:
This study is classified as reliable with restriction. The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. We believe that the CRC handbook represents one such a secondary source. Therefore, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.
Guideline:
other: Methodology is not specified in the CRC Handbook therefore it is not know or certain if the relevant test methods were used
