Key value for chemical safety assessment

Water solubility:
0.5 g/L
at the temperature of:
20 °C

Additional information

Various experimental results on the water solubility of quinidine are available. The lowest water solubility of 0.14 g/L at 25°C is given by ChemIDplus Advanced and EPI Suite v.4.11. According to the peer-reviewed database, GSBL, the water solubility of quinidine is 0.5 g/L at 20°C. The most conservative value for water solubility is given by the highest value. Therefore, quinidine is moderately soluble with a water solubility up to 0.5 g/L at 20°C.
