Reference
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.
