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

A fluorine-substituted amphetamine or amphetamine derivative with the formula (I):
where at least one of the residues R1 or R2 is different from H and Ph is a phenyl ring, which is substituted with fluorine in at least one position or the residues R1 and R2 independently of one another are H or are different from H and Ph is a phenyl ring, which is substituted with fluorine in at least three positions or the residues R1 and R2 independently of one another are H or are different from H and Ph is a phenyl ring, which is substituted with fluorine in at least one position and has a substituent different from H in at least one other position.

of the enantiomers of these chiral NPS may differ can be assumed from a broad spectrum of active pharmaceutical ingredients. For this reason, analytical method development regarding enantiomeric separation for these classes of substances is of great pharmaceutical and medical interest. The aim of this work was to create an easy‐to‐prepare chiralcapillaryelectrophoresis method for the enantioseparation
