to:
A: Triturate a quantity of the contents of Capsules, equivalent to about 500 mg of theophylline, with 10-mL and 5-mL portions of solvent hexane, and discard the solvent hexane. Triturate the residue with two 10-mL portions of a mixture of equal volumes of 6 N ammonium hydroxide and water, and filter each time. Evaporate the combined filtrates to about 5 mL, neutralize, if necessary, with 6 N acetic acid, using litmus, and then cool to about 15°, with stirring. Collect the precipitate on a filter, wash it with cold water, and dry at 105° for 2 hours: the theophylline so obtained melts between 270° and 274° (see Melting Range or Temperature 〈741〉, Procedures, Procedure for Class I). Retain the remaining portion of the theophylline for use in Identification test B.
B: The IR absorption spectrum of a potassium bromide dispersion of the residue obtained in Identification test A exhibits maxima only at the same wavenumbers as that of a potassium bromide dispersion of USP Theophylline RS.
