Justification for data waiving:
the study does not need to be conducted because the substance is hydrolytically unstable (half-life less than 12 hours)

Description of key information

Since the test substance is hydrolytically unstable, the study cannot be conducted.

Key value for chemical safety assessment

Additional information

In accordance with column 2 of Annex IX Regulation (EC) No 1907/2006 (REACH), the study does not need to be conducted if the substance is hydrolytically unstable. In the present case the hydrolysis half-life of the test substance is considered to be < 12 hours and hence the study is not required.
