Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
06 Jul 2016
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Principles of method if other than guideline:
- Principle of test: Melting point is determined by the use of differential scanning calorimetry (DSC) in which the difference in the amount of heat required to increase the temperature of a sample and
reference is measured as a function of temperature.
- Short description of test conditions:
 Fill a DSC pan with ± 1 to 5mg sample and record the sample weight
 Close the DSC sample pan with a pan cover using a pan press
 Place the sample pan into the sample position of the DSC
 Prepare an empty reference pan and place it into the reference position of the DSC
 Start the analysis
GLP compliance:
not specified
Type of method:
differential scanning calorimetry
