Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- The vapour pressure was estimated using the MPBPVP v 1.43 (EPI Suite version 4.11)
- Qualifier:
- according to guideline
- Guideline:
- other: QSAR
- Principles of method if other than guideline:
- MPBPVP v 1.43 (EPI Suite version 4.11)
- GLP compliance:
- no
- Remarks:
- Not applicable to QSAR models
- Type of method:
- other: QSAR
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- ca. 0 mm Hg
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- ca. 0 Pa
- Conclusions:
- The vapour pressure of the reference substance Quaternary Ammonium Compounds, Dicoco Alkyldimethyl nitrites, CAS Number 71487-01-9, EC Number 275-532-1 was estimated to be (mm Hg,25 deg C): 3.74E-013 (Modified Grain method) ; (Pa, 25 deg C) : 4.98E-011 (Modified Grain method)
- Executive summary:
The vapour pressure of the reference substance quaternary ammonium compounds, dicoco alkyldimethyl nitrites, CAS Number 71487-01-9, EC Number 275-532-1 was investigated using the The MPBPVP, version 1.43 (EPI Suite Version 4.11)
The study was assigned a reliability score of 2 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
The vapour pressure was estimated to be VP (mm Hg,25 deg C): 3.74E-013 (Modified Grain method) ; VP (Pa, 25 deg C) : 4.98E-011 (Modified Grain method)
However, the minmum valie that EUSES can use for the assessment is 1.0E-6. Therefore, this value is used for the assessment.
