Description of key information

The substance is stable in water.

Key value for chemical safety assessment

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

Additional information

A study on the hydrolysis is available for a close structural analogue (CAS 16090-02-1) that demonstrates that the test substance is stable (hydrolysis < 10 %) at pH 4, 7 and 9 at 50 °C and that the half life of the tested substances for hydrolysis is proved to be greater than 1 year (CIBA-GEIGY 1992).

Therefore it is assumed that the substance CAS 133-66-4 is stable in water as well.
