A volume of Ophthalmic Solution, equivalent to about 2.5 mg of oxymetazoline hydrochloride, responds to the Identification test under Oxymetazoline Hydrochloride Nasal Solution.
to:
Place a volume of Ophthalmic Solution, equivalent to about 2.5 mg of oxymetazoline hydrochloride, in a 60-mL separator, and add water to make about 10 mL. Add 2 mL of sodium carbonate solution (1 in 10), extract with 10 mL of chloroform, and transfer the chloroform extract to a second 60-mL separator. Extract the chloroform solution with 10 mL of 0.1 N hydrochloric acid, allow to separate, and discard the chloroform layer. Transfer 8 mL of the acidic aqueous layer to a test tube, neutralize by the dropwise addition of 1 N sodium hydroxide, add 1 drop of 1 N sodium hydroxide in excess, and mix. Add a few drops of sodium nitroferricyanide TS and 2 drops of sodium hydroxide solution (15 in 100), mix, and allow to stand for 10 minutes. Add 0.1 N hydrochloric acid dropwise until the pH is between 8 and 9, and allow to stand for 10 minutes. A violet color develops.
