microtubule(tubulin stabilising)
In vitro (25°C) DMSO 95 mg/mL (187.48 mM)
Water Insoluble
Ethanol 95 mg/mL (187.48 mM)
In vivo 2% DMSO+30% PEG 300+2% Tween 80+ddH2O 6 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.
