Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
(Q)SAR
Adequacy of study:
key study
Study period:
10 February 2017
Reliability:
1 (reliable without restriction)
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:
1. SOFTWARE; EPISUITE

2. MODEL (incl. version number); EPIWEB v4.11

3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
O=C(OCC=C)c(cccc1C(=O)OCC=C)c1
Water solubility 33.8 mg/l
Henry LC 3.86E-07

4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL

Episuite is a software program developed by the EPA and is recognised internationally as the accepted QSAR software.

5. APPLICABILITY DOMAIN

No data

6. ADEQUACY OF THE RESULT

The data for some of the physicochemical characteristics is inadequate in its reliability and results from EPISUITE will be more readily accepted.
Qualifier:
