other: Based on theoretical calculation

Any other information on results incl. tables

The test substance was analysed for vapour pressure at 25 deg. C using a gas saturation aparatus. the analyte quantification was carried out after gas saturation by HPLC.

No analyte was observed in the test solutions therefore direct measurement of vapour pressure using the gas saturation method was not possible. The vapour pressure was determined using a theoretical calculation based on the LOQ of the quantitative HPLC method.

No evaluation of vapour presssure at 20 deg. C using this method was undertaken as the results would not be significantly different and would be lower than those obtained at 25 deg. C.

Applicant's summary and conclusion

Conclusions:
The vapour pressure at 25 deg. C was determined to be <3.05 x 10-6 Pa based on a theoretical calculation.
Executive summary:

Introduction

The study was undertaken to determine the vapur pressure of the test material. The test method used was compatible with EU Method A.4 (Vapour Pressure), however, vapur pressure was determined using a theoretical calculation as no analyte was observed in the test solutions.

Results & Conclusions

The vapour pressure at 25 deg. C was determined to be <3.05 x 10-6 Pa based on a theoretical calculation.
