Reference
Endpoint:
stability in organic solvents and identity of relevant degradation products
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the stability of the substance is not considered to be critical

Description of key information

The endpoint is waived: If stability in an organic solvent is deemed critical, it is typically as a medium for another study and determined as a pre-test for the other study and therefore not reported separately.  

Additional information

According to the Annex IX Standard Information Requirements for REACH, 7.15 of the assessment of the stability in organic solvents and identity of relevant degradation products is “only required if stability of the substance is considered to be critical”. According to Section R.7.1.6 of the Endpoint Specific Guidance, “There are rare occasions when it is important to have information on the stability of a compound in an organic solvent, to ensure confidence in the test results. However, for many substances, the stability in organic solvents will not be critical and testing need not be conducted”.

If stability in an organic solvent is deemed critical, it is typically as a medium for another study and determined as a pre-test for the other study and therefore not reported separately.
