What is Product D1756, Dexamethasone, soluble in?
Dexamethasone is practically insoluble in water. It is soluble in ethanol, methanol, acetone, dioxane, and slightly soluble in chloroform. Sigma routinely tests the solubility at 50 mg/mL in ethanol with heat, yielding a clear, colorless to faint yellow solution. However, dexamethasone will precipitate out of solution as the temperature returns to room temperature. At 25 mg/mL in methanol or ethanol, a clear colorless solution is obtained without heating. The solubility of dexamethasone in DMSO is 606 mg/mL at 25°C.
What is the solution stability of Product D1756, Dexamethasone?
Aqueous solutions of dexamethasone are stable for at least 30 days at 4°C. A stock solution at a concentration of 1mg/mL in absolute ethanol can be diluted 1:50 with sterile media and stored frozen as working aliquots.
Is Product D1756, Dexamethasone, suitable for cell culture?
This product has not been tested for cell culture. Please consider either Product No. D8893 or D4902, both of which are cell culture tested.
