The CV for the vapor pressure determination of the test substance at 20 ± 1°C was higher than the estimated repeatability criteria for the SRG method (i.e. 10 to 20%) in the OPPTS 830.7950 and OECD 104 guidelines. Higher variability often occurs for mixtures or less pure materials. This higher variability might also be attributed to the very low vapor pressure of the test material. Per the OPPTS 830.7950 and OECD 104 guidelines, the recommended range of the SRG method is 10E-04 to 0.5 Pa (1,2). The vapor pressure of the test substance is at the bottom of this range.
The average molecular weight (MW) of 910.06 g/mol was provided in error by the study sponsor. A MW of 861.92 g/mol was originally provided then later "corrected" to 910.06 g/mol. The original value of 861.92 g/mol was then later determined to be correct after all but was not corrected in the study report. Using a MW of 861.92 and the equations provided in the study report would have resulted in a vapour pressure of 1.017E-03 Pa at 20 deg C. Given that the MW is a theoretical calculated average and given that this vapour pressure is still at the lower limit of the method, it was considered unnecessary to revise the report as written.
Applicant's summary and conclusion
- Conclusions:
- The measured vapour pressure of the test item was determined to be 1.017E-03 Pa at 20 deg C.
- Executive summary:
In an OECD Method 104 guideline study conducted under GLP conditions using the spinning rotor method, the vapour pressure of the test item was determined to be 1.017E-03 Pa at 20 deg C.
