摘要
建立了测定苯噻酰草胺原药中杂质2-巯基苯并噻唑的高效液相色谱法,以乙腈+磷酸水溶液为流动相,使用ZORBAX SB-C_8不锈钢柱和二极管阵列检测器。方法的线性相关系数为0.997 7,平均回收率为99.8%,变异系数为4.85%。方法简单,易操作,可以满足原药生产的过程控制和最终产品的质量检验要求。
A metho d for determination of 2-mercaptobenzothiazole in mefenacet TC was established by HPLC. The mobile phase was the mixture of acetonitrile and H3PO4 aqueous solution, the chromatographic column was ZORBAX SB-C8 column, the wavelength was 324 nm. The results showed that the linear correlation coefficient of the method was 0.997 7, the average recovery was 99.8%, the variation coefficient was 4.85%.
