enantiomers may differ in their pharmacological effect. The aim of this study was to test a novel HPLCcolumn for the enantioseparation of a set of 112 NPS coming from different chemical groups and collected by internet purchases during the years 2010–2018. The CSP, namely Lux® 5 μm i‐Amylose‐1, LC Column 250 x 4.6 mm, was run in normal phase mode under isocratic conditions, UV detection was performed
这些术语背后隐藏着浴盐,熏蒸剂,清洁剂和空气清新剂,这些物质被算作“合法上限”。这些花哨的名字被用来装扮成合法的无害化合物,以规避市场营销的法律法规并增加销量。除了合成的经典非法药物(如苯丙胺,可卡因和摇头丸)以外,这些化合物的贸易(也称为新型精神活性物质(NPS))在当今并不罕见。在许多国家,NPS仍然不受药物管制。其中,有具有手性中心的兴奋剂,例如新的苯丙胺衍生物或卡西酮。关于两种可能的对映异构体的药理作用可能不同的事实知之甚少。这项研究的目的是测试一种新颖的HPLC色谱柱,该色谱柱用于对映分离2010年至2018年间通过互联网购买的来自不同化学族的112种NPS。CSP,即Lux®5μmi-Amylose-1,LC色谱柱250 x 4.6 mm,在等度条件下以正相模式运行,在245 nm和230 nm处进行UV检测,进样量为10μl,流速为为1毫升/分钟。使用由正己烷/异丙醇/二乙胺(90:10:0

In this paper the dynamic resolution of racemic tertiary cathinones is demonstrated through co-crystallization with enantiopure aromatic tartaric acids.
