Solubility (25°C)* In vitro DMSO 20 mg/mL heating (35.83 mM)
Water <1 mg/mL (<1 mM)
Ethanol 3 mg/mL (5.37 mM)
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Adooq tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
