Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study conducted under GLP.
Reason / purpose for cross-reference:
reference to same study
according to guideline
EU Method A.2 (Boiling Temperature)
Version / remarks:
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Atm. press.:
ca. 1 atm
Decomp. temp.:
ca. 260
Remarks on result:
other: Pressure assumed to be ambient atmospheric.

7.35mg of sample heated at 10°C/min from 25°C to 500°C under nitrogen gas. Sharp endotherm observed at 115°C corresponding to the melting point. Black residue observed at the end of the run; 37% of starting mass.

The measurement was repeated with a 9.91mg sample from 50°C to ca. 450°C, with the similar results.

The study is considered to be adequate and reliable.
