water solubility
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours)

Description of key information

The study is waived as the test substance was determined to be hydrolytically unstable under acidic, neutral and basic conditions, with a half-life of less than 10 minutes at 10ºC.

Key value for chemical safety assessment

Water solubility:
100 mg/L
at the temperature of:
22 °C

Additional information

The preliminary study showed that at each of pH 4, 7 and 9 and 10 ± 0.5ºC, greater than 50% hydrolysis had occurred after 10 minutes.

Based on the Acute toxicity test with Rare Minnow report, 100 mg/L at 22 °C is used in CSR.
