Details on results:
A detection limit test (R. 7 .1. 7 .4) calculated on the basis of the listed data yields to a lower limit of 0.02 mg/L.
Therefore it is possible to report as upper limit for the water solubility of the test item, the limit of determination of 0.1 mg/L and as lower limit the limit of detection of 0.02 mg/L.

Description of key information

> 0.02 < 0.1 mg/L at 20°C and at pH 6.9

Key value for chemical safety assessment

Additional information

The determination was conducted by column elution method to test procedure VTA34N00003.01, which complies with EU test method L383 A/54-62 (EEC A.6). The concentration was quantified by UPLC-ESI-MS.

The water solubility of test item was found beneath the limit of quantification of 0.1 mg/L and above the limit of detection of 0.02 mg/L.
