title: Separation and quantitative determination of 2,4-disulfamyl-5-trifluoromethylaniline in hydroflumethiazide using high-pressure liquid chromatography.
abstract: A high-pressure liquid chromatographic method was developed to quantify 2,4-disulfamyl-5-trifluoromethylaniline in hydroflumethiazide using a bonded pellicular packing. An internal standard was added to the samples to ensure reproducibility. The results were compared with methods currently in use.
