  • Title: Liquid chromatographic determination of sulfamoyldapsone in swine tissues.
    Author: Endoh YS, Yamaoka R, Sasaki N.
    Journal: J Assoc Off Anal Chem; 1987; 70(6):1031-2. PubMed ID: 3436897.
    Abstract:
    A liquid chromatographic (LC) method is described for the quantitative determination of sulfamoyldapsone (2-sulfamoyl-4,4'-diaminodiphenyl sulfone) in swine muscle, liver, kidney, and fat. Sulfamoyldapsone was extracted from tissues with acetonitrile saturated with n-hexane. The extract was washed with n-hexane saturated with acetonitrile, concentrated, and cleaned up by alumina column chromatography. Sulfamoyldapsone was separated on an ODS column by using acetonitrile-methanol-water (6 + 18 + 76) and was detected at 292 nm. Overall average recovery of sulfamoyldapsone added to tissues at levels of 0.1 and 0.5 microgram/g was 93.3% +/- 6.0. Detection limit was 0.02 microgram/g in these tissues.
