vapour pressure
Type of information:
calculation (if not (Q)SAR)
estimated by calculation
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: calculation performed with well accepted software
Principles of method if other than guideline:
Calculation with Software: MPBPWIN 1.43 (Syracuse Research Corporation)
Type of method:
other: calculation
20 °C
Vapour pressure:
< 0.001 Pa
Remarks on result:
other: determined by calculation
The calculated Vapour Pressure is < 0.001 Pa at 20°C
Executive summary:

The melting point of the substance is 288°C. Therefore the vapour pressure can be calculated. According to REACH Annex VII, 7.5 column 2 a calculation of this endpoint is sufficient.

The calculation was performed with Software: MPBPWIN 1.43 (Syracuse Research Corporation) with the result:

Vapour Pressure < 0.001 Pa at 20°C

Description of key information

The calculated Vapour Pressure is < 0.001 Pa at 20°C

Key value for chemical safety assessment
