الإجراء التجريبي

The beclomethasone dipropionate-n-hexane solvate is prepared by dissolving the beclomethasone dipropionate in a suitable organic solvent, such as methylene chloride or acetone, and then adding n-hexane to this solution resulting in the formation of a precipitate. The precipitate is filtered and dried to afford the beclomethasone dipropionate-n-hexane solvate.
