enantiomeric separation of prothioconazole and prothioconazole‐desthio was performed on various chiral stationary phases (CSPs) by high‐performance liquid chromatography (HPLC). It was found that polysaccharide CSPs showed better ability than brushing CSPs in enantiomeric separation. The successful chiral separation of prothioconazole could be achieved on self‐made Chiralcel OD, commercialized Chiralcel
Prothioconazole是拜耳公司开发的一种广谱三唑硫酮杀菌剂。丙硫基康唑-去硫基是环境中丙硫基康唑的主要代谢产物。在我们的研究中,通过高效液相色谱(HPLC)在各种手性固定相(CSP)上进行了Prothioconazole和Prothioconazole-desthio的对映体分离。发现在对映体分离中,多糖CSP比刷CSP具有更好的能力。Prothioconazole的成功手性分离可通过自制的Chiralcel OD,商品化的Chiralcel OJ‐H和Lux Cellulose-1实现。Chiralpak IA,Chiralpak IB,Chiralpak IC,Chiralcel OD,Chiralpak AY‐H,Chiralpak AZ‐H和Lux Cellulose-1实现了原硫代康唑-去硫对映体的基线分离。使用乙腈(ACN)和水作为流动相,在Lux Cellulose
