溶解度
| In vitro (25°C) | DMSO | 75 mg/mL (195.11 mM) |
| Water | Insoluble |
| Ethanol | 3 mg/mL (7.8 mM) |
| In vivo | 2% DMSO+30% PEG 300+ddH2O | 4 mg/mL |
*<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. |
