Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2012/07/16 - 2012/11/26
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.4 (Vapour Pressure)
GLP compliance:
no
Type of method:
gas saturation method
Temp.:
25 °C
Vapour pressure:
< 0 Pa
Remarks on result:
other: the VP at 20 °C is also expected to be <1.9E-4 Pa

The vapour pressure at 20 degrees C is 1.9 x 10 -4 Pa.

Conclusions:
Under the study conditions, the vapour pressure of the test substance was determined to be <1.9E-4 Pa at 20 or 25 °C.
Executive summary:

A study was conducted to determine the vapour pressure of the test substance at 25°C using gas saturation apparatus according to EU A4 Regulation (EC) No 440/2008. The analyte quantitation was carried out post gas saturation by HPLC-MS. At 25°C, no test substance was detected in any of the gas saturation solutions above LOQ therefore the test was not repeated at 20°C, as it was clear that no test substance would be expected at the lower temperature. Under the study conditions, the vapour pressure of the test substance was determined to be <1.9E-4 Pa at 20 or 25 °C (Wicks, 2013).

Description of key information

The vapour pressure of the test substance was determined using gas saturation apparatus according to EU Method A.4 (Wicks, 2013).

Key value for chemical safety assessment
