A method for optical purity determination of a range of chiral drug molecules by NMR spectroscopy is reported. This technique involves the use of optically active lanthanide shift reagents and a newly developed base line analysis. Its applicability was demonstrated for a variety of drugs including nonsteroidal antiinflammatory agents and some adrenergic agents. It is established that successful application
报道了一种通过NMR光谱法测定一系列手性药物分子的光学纯度的方法。该技术涉及使用光学活性镧系元素转移试剂和新开发的基线分析。已证明其适用于多种药物,包括非甾体类抗炎药和某些肾上腺素能药。可以确定的是,该方法的成功应用取决于试剂与样品的摩尔比恒定变化,所有溶液的仪器条件恒定以及使用源自两种相同对映体总浓度相同的溶液的校准曲线。对于所引用的示例,相关系数不小于0.97,并且包括支持该方法基础的数学处理。
