Remarks:
Statement in report.
Principles of method if other than guideline:
Test details were not provided.
GLP compliance:
no
Dissociating properties:
not determined
Executive summary:

The testing laboratory provided a statement that "due to the low water solubility of the test item (0.021 g/l), it was not possible to determine the dissociation constants in water".

Endpoint:
dissociation constant
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is insoluble

Description of key information

Due to the low water solubility of the test item (0.021 g/l), it was not possible to determine the dissociation constants in water.

Key value for chemical safety assessment

Additional information

The testing laboratory provided a statement that "due to the low water solubility of the test item (0.021 g/l), it was not possible to determine the dissociation constants in water". (in fact, the water solubility is even lower, i.e., 0.87 µg/L).
