Description of key information

The hydrolysis of the test substance in contact with water was investigated by HPLC-UV method. The test item rapidly decomposes in contact with water. Decomposition is indicated by the difference of the chromatograms prepared in acetonitrile and in aqueous phases.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 h
at the temperature of:
25 °C

Additional information

The hydrolysis of the test substance in contact with water was investigated by HPLC-UV method. The test item rapidly decomposes in contact with water. Decomposition is indicated by the difference of the chromatograms prepared in acetonitrile and in aqueous phases. The chromatogram of the test substance, that was dissolved in ultra-pure water, shows a peak located at ca. 4.35 min (retention time), whereas the chromatogram of the test substance, that was dissolved in acetonitrile, shows a peak located at ca. 3.14 minutes (retention times).

As key value for chemical safety assessment a half-life at 25 °C was estimated to be ca. 1 h (worst-case assumption).
