In an embodiment, a composition including a chiral solvating agent to resolve nuclear magnetic resonance signals of an enantiomer of at least one analyte, where the chiral solvating agent facilitates in the at least one analyte binding to a C2 face or a C3 face of the chiral solvating agent, and where the chiral solvating agent causes an upfield shift or a downfield shift in at least one nuclear magnetic resonance signals corresponding to a 1H, 19F1H}, or 31P1H} signal, and where the chiral solvating agent includes a cobalt cation. In another embodiment, a method that includes mixing a chiral solvating agent, including a cobalt cation, with at least one analyte to form a solution, obtaining nuclear magnetic resonance spectra of the solution, and identifying an enantiomer of the at least one analyte. In some embodiments, the method further includes determining enantiomeric purities of the at least one analyte.
在一个实施方案中,一种包括手性溶解剂的组合物,用于解析至少一种分析物的对映体的核磁共振信号,其中手性溶解剂促进至少一种分析物与手性溶解剂的C2面或C3面结合、其中手性溶解剂导致至少一个核磁共振信号对应于 1H、19F1H} 或 31P1H} 信号的上场移动或下场移动,并且其中手性溶解剂包括钴阳离子。在另一个实施方案中,一种方法包括将包括钴阳离子在内的手性溶解剂与至少一种分析物混合形成溶液,获得溶液的核磁共振谱,并鉴定至少一种分析物的对映体。在某些实施方案中,该方法还包括确定至少一种分析物的对映体纯度。
