Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- August 2015
- 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
- Qualifier:
- according to guideline
- Guideline:
- other: ECHA guidance on information requirements and chemical safety assessment, chapter R.6: QSARs and grouping of chemicals
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- other: QSAR, modified grain method
- Specific details on test material used for the study:
- SMILES: CC1C(=O)OC(C(=O)O1)C (canonical); C[C@@H]1C(=O)O[C@@H](C(=O)O1)C (isomeric)
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0.28 Pa
- Remarks on result:
- other: Estimation of vapour pressure is reliable since experimental values for melting point and boiling point are available.
- Conclusions:
- The vapour pressure of DD-lactide is 0.28 Pa at 25 °C, obtained by QSAR calculation.
- Executive summary:
The vapour pressure of DD-lactide was estimated by QSAR calculation (MPBPWin v1.43, EpiSuite). Experimental values for melting point and boiling point were taken into account. The resulting vapour pressure of DD-lactide is 0.28 Pa at 25 °C.
