反相高效液相色谱法同时测定丁酸氯维地平中10种相关杂质

建立反相高效液相色谱辅-光电二极管阵列检测器( RP-HPLC)法同时测定丁酸氯维地平原料药中的10种杂质。色谱柱为 Symmetry C18柱(250 mm×4.6 mm,5μm),流动相为0.05 mol/L NaH2PO4溶液(pH 2.5)-乙腈/甲醇(3:2, V/V),梯度洗脱,柱温35℃,流速为1.5 mL/min,检测波长220 nm。丁酸氯维地平及其10个已知杂质能够达到良好的分离,且各组分在各自测定浓度范围内与峰面积的线性关系良好(r≥0.9970);丁酸氯维地平及杂质1~10的检出限(S/N=3)在0.15~0.90 mg/L之间。本方法快速、简便、有效,可用于丁酸氯维地...

A reversed phase high performance liquid chromatographic ( RP-HPLC) method coupled with DAD was developed for the simultaneous determination of ten process-related impurities ( PRI ) of Clevidipin Butyrate ( CLE). The chromatographic separation was carried out on a Waters symmetry C18 column (250 mm ×4. 6 mm, 5 μm) and all components were monitored at 220 nm. The mobile phase consisted of 0. 05 mol/L sodium dihydrogen phosphate with pH 2. 5 adjusted by phosphoric acid ( MPA ) and a mixed solution of acetonitrile and methanol (3:2, V/V). Flow rate was kept at 1. 5 mL/min, the injection volume was 20 μL for all injections, and the c
