Barnidipine hydrochloride is a long term dihydropyridine calcium channel blocker used for the treatment of hypertension. During the process development of barnidipine hydrochloride, four barnidipine impurities were detected by high-performance liquid chromatography (HPLC) with an ordinary column (Agilent ZORBAX Eclipse XDB-C18, 150 mm×4.6 mm, 5 µm). All these impurities were identified, synthesized
盐酸巴尼地平是一种长期的二氢吡啶类钙通道阻滞剂,用于治疗高血压。在盐酸巴尼地平的工艺开发过程中,使用普通色谱柱(Agilent ZORBAX Eclipse XDB-C18,150 mm×4.6 mm,5 µm)通过高效液相色谱 (HPLC) 检测到四种巴尼地平杂质。所有这些杂质都被鉴定、合成并随后通过它们各自的光谱数据(MS、1H-NMR 和 13C-NMR)进行表征。这些杂质的鉴定应有助于巴尼地平生产过程中的质量控制。
