Solubility Data

Solubility (In Vitro)

DMSO : ~100 mg/mL (~279.10 mM; with ultrasonication)

Solubility (In Vivo)

Solubility in Formulation 1: ≥ 2.5 mg/mL (6.98 mM) (saturation unknown) in 10% DMSO +90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution。 For example, if 1 mL of working solution is to be prepared, You can add 100 μL of the 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD in saline and mix well. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.98 mM) (saturation unknown) in 10% DMSO +90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution。 For example, if 1 mL of working solution is to be prepared, You can add 100 μL of the 25.0 mg/mL clear DMSO stock solution to 900 μL corn oil and mix well.  (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	2.7910 mL	13.9548 mL	27.9096 mL
	5 mM	0.5582 mL	2.7910 mL	5.5819 mL
	10 mM	0.2791 mL	1.3955 mL	2.7910 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
