boiling point
Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 103 (Boiling Point)
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Key result
Decomp. temp.:
>= 148 °C
A boiling temperature could not be determined due to thermal decomposition of the substance.
Executive summary:

The boiling temperature of the substance was determined under GLP in a study conducted according to OECD TG 103, by differential scanning calorimetry. Aliquots of about 2 to 5.5 mg of the test substance were placed in aluminium crucibles with pre-perforated (two determinations) or manually pierced lids (five determinations). The first five determinations were made in an air atmosphere and two determinations in a nitrogen atmosphere under atmospheric pressure. On thermal analysis, no evidence of boiling was observed in any determination. All thermogram profiles showed only a single exothermic thermal event, attributed to decomposition of the test substance, which started from approximately 148 °C.

Description of key information

A boiling temperature could not be determined due to thermal decomposition of the substance, starting from about 148 °C.

Key value for chemical safety assessment
