Any other information on results incl. tables

In the frame of the validation of an analytical method conducted according to the European Commission: Guidance for Generating and Reporting Methods of Analysis in Support of Pre-Registration Data Requirements for Annex II (Part A, section 4) and Annex III (Part A, section 5) of Directive 91/414, SANCO/3029/99 rev. 4 (11/07/00) the stability of the test substance was investigated. Stock solutions of the test substance were prepared in methanol at concentrations of 915 - 2320 mg/l. In order to dissolve the test substance the solutions were ultrasonicated for 10 minutes. The stock solutions were analysed at a nominal concentration of 500 mg/l. Since the coefficient of variation on the response factors of the calibration solutions was = 10% the stock solutions were stable when stored at room temperature for at least 1 day.

Applicant's summary and conclusion

Conclusions:
The test substance dissolved in methanol was stable for at least 1 d.
