Description of key information

The water solubility of the two analogues  were assessed using the column elution method (Wil 2013, Laus 2015). The result of both studies is a water solubility of ca. 0.23 mg/L.

Key value for chemical safety assessment

Water solubility:
0.23 mg/L
at the temperature of:
20 °C

Additional information

The water solubility of the analogues DDNSA and DNNSA is very similar. Therefore in a weight of evidence approach, the water solubility of the substance is set at 0.23 mg/L. The very low water solubility is confirmed by the outcome of a QSAR on a representative structure of CaDDNSA.
