Quantitative determinations of phenol and resorcinol in pharmaceutical dosage forms by high-pressure liquid
Journal of Pharmaceutical Sciences
|November 1, 1976
Abstract:
The quantitative determinations of phenol in phenolated calamine lotion USP and of phenol and resorcinol in phenol-resorcinol-boric acid solution by high-pressure liquid chromatography are reported. The procedures are simple, rapid (no special preliminary treatment is required), and accurate. There is no interference from other ingredients of the lotion (bentonite magma, calamine, and zinc oxide) or solution (acetone and boric acid).
