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:
- September 2018
- 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 EPI (Estimation Programs Interface) Suite™ is a Windows®-based suite of physical/chemical property and environmental fate estimation programs developed by EPA’s and Syracuse Research Corp. (SRC). (https://www.epa.gov/tsca-screening-tools/epi-suitetm-estimation-program-interface) This model can be used to estimate physical chemical data of chemicals.
- Qualifier:
- according to guideline
- Guideline:
- other: ECHA REACH guidance document 'QSAR and Grouping of Chemicals' Chapter R.6
- GLP compliance:
- no
- Specific details on test material used for the study:
- Smiles Notation: O=C(NC(=O)C(=NO)C1(=O))N1
- Key result
- Test no.:
- #1
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- The vapour pressure of Violuric acid has been estimated with EPI SuiteTM to 2.24E-11 Pa at 25°C.by the Modified Grain method.
- Executive summary:
Vapour pressure of violuric acid was estimated by QSAR using EPI SuiteTM v.4.11. The estimation was based on the Modified Grain method, which is the preferred method for solids.
By this method the vapour pressure was estimated to 2.24E-11 at 25°C.
