title: [A method of quality control of 3-phenyl-5-methylisoxazole-4-carbonic acid chloranhydride using high performance liquid chromatography].
abstract: A method of quantitative determination of 3-phenyl-5-methyl-isoxazole-4-carbonyl chloride useful for its qualitative estimation at all stages of oxacillin industrial synthesis was developed. The methods is based on transformation of this semi-product into isopropyl ester followed by high efficiency liquid chromatography with the use of the "Milikhrom" chromatograph mad in the USSR. A variant of the typical method for determination of 3-phenyl-5-methyl-isoxazole-4-carbonyl chloride concentration in solution is described.
