EC number: 201-854-9 | CAS number: 88-73-3
Vapour pressure
Administrative data
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- other: GLP-Guideline study (reliability 1), but the vapour pressure is extrapolated over a wide temperature range, so for the value at 20 °C the reliability is 3
