Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
according to guideline
OECD Guideline 103 (Boiling Point)

GLP compliance:
Type of method:

Key result
Boiling pt.:
187 °C
Atm. press.:
1 013 hPa

The boiling temperature is determined from the extrapolated onset temperature of the endothermic peak. Since the ambient pressure deviates from the standard pressure, the measured boiling temperatures T were converted to normal boiling points Tn by means of the Sidney-Young equation.

Tn = T + (fT . Δp)

fT = 0.037 K/hPa

Mean value



A boiling point of 187°C at 1013 hPa was determined in accordance to an acceptable guideline method. This result is considered to be reliable.

Description of key information

Boiling point: 187°C at 1013 hPa (OECD 103)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
187 °C

Additional information

A boiling point of 187°C at 1013 hPa was determined for the submission substance in an experimental study using a differential scanning calorimetry method conducted according to OECD test guideline 103. This result is considered to be reliable and is selected as key.


The key result is supported by a predicted boiling point of 180°C at 1013 hPa, determined using a validated QSAR estimation method.


In available secondary sources to which reliability could not be assigned, boiling point values of 185°C at 1013 hPa and 73°C at 18 hPa were reported for the substance.
