A New Oxidative Derivatization Method For The Indirect Spectrofluorimetric Determination Of Prochlorperazine Maleate In Pharmaceutical Preparations
A new oxidative derivatization method for the indirect spectrofluorimetric determination of Prochlorperazine maleate has been presented. Potassium hydrogenperoxomonosulphate is proposed as a derivatizing agent for Prochlorperazine, yielding the strongly fluorescent sulfoxide. This reaction product was successfully employed for the spectrofluorimetric determination of the Prochlorperazine maleate. A highly sensitive, simple and rapid method has been developed for determining prochlorperazine maleate in tablets by fluorescence of its oxidation product with Oxone solution in 0.01 M sulfuric acid solution (λex = 340 nm; λem = 380 nm). The calibration curve is linear in its concentration range of 0.8–10.0 µg/ml. Limit of quantification (LOQ = 10S) is 0.8 µg/ml. The possibility of quantitative determination of Prochlorperazine maleate in Vertinex® tablets 5 mg has been shown, RSD <2.3% (δ
