Justification for data waiving:

Description of key information

The endpoint is waived, study technically not feasible.

Key value for chemical safety assessment

Additional information

The dissociation constant cannot be determined, because the solubility of the substance is too low(lower than 1 µg/L) and absorbance spectra are completely absent . See 1.4 Analytical information UV/Vis. According to ECHA Guidance on information requirements and chemical safety assessment. Chapter R.7a: Endpoint specific guidance p 175.
