title: Determination of uracil in 5-fluorouracil substance by high-performance liquid chromatography.
abstract: Separation of 5-fluorouracil and uracil in chromatographic systems consisting of a silica column as a stationary phase and ethyl acetate or ethyl acetate partially saturated with water as a mobile phase has been studied. The results indicated that when saturation of ethyl acetate with water was chosen to reach more than 60%, such mobile phases [e.g., 2.4% (v/v) water in ethyl acetate] are useful in determining uracil in 5-fluorouracil substances.
