Rapid spectrophotometric determination of salicylamide in analgesic tablets.
An independent, simple, and rapid procedure is suggested for the routine analysis of salicylamide in analgesic tablets containing acetaminophen, phenobarbital, caffeine, codeine phosphate, prednisone, ascorbic acid, and chloroquine phosphate. The method does not require the preliminary separation of salicylamide from other constituents by the time-consuming solvent extraction technique or by chromatography prior to determination. The absorbance was linear for investigated concentrations of salicylamide from 0 to 4.0 mg/100 ml of solution at 308 nm.
