ABSTRACT
A reverse phase HPLC method is described for the determination of 6-mercaptopurine in bulk and tablets. Chromatography was carried on a C18 column using a mixture of acetonitrile and 0.05 mol/L sodium acetate buffer (1090 v/v) as the mobile phase at a flow rate of 1 mL/min-1 with detection at 324 nm. The retention time of the drug was 3.25 min. The detector response was linear in the concentration of 0.01-5 μg/mL. The limit of detection and limit of quantification were 17 and 52 ng/mL respectively. The method was validated by determining its sensitivity, linearity, accuracy and precision. The proposed method is simple, economical, fast, accurate and precise and hence can be applied for routine quality control of mercaptopurine in bulk and tablets.
RESUMO
Descreve-se método de CLAE em fase reversa para a determinação de mercaptopurina a granel e em comprimidos. A cromatografia foi realizada em coluna C18, utilizando mistura de acetonitrila em tampão acetato de sódio 0,05 mol/L (1090 v/v) como fase móvel, com fluxo de 1 mL/min e detecção a 324 nm. O tempo de retenção do fármaco foi de 3,25 min. A resposta do detector foi linear na concentração de 0,01-5 μg/mL. O limite de detecção e o limite de quantificação foram de 17e 52 ng/mL, respectivamente. O método foi validado pela determinação de sua sensibilidade, linearidade, acurácia e precisão. O método proposto é simples, econômico, rápido, acurado e preciso e, então, pode ser aplicado para controle de qualidade de rotina da mercaptopurina em batelada e em comprimidos.
