文摘
- •
Enantio-separation of pyrisoxazole enantiomers was developed using LC-Q-TOF/MS.
- •
Thermodynamic analysis displayed their difference on enantioseparation mechanism.
- •
QuEChERS was employed for sample pretreament with satisfactory recovery and accuracy.
- •
Enantioselectivity and diastereoselectivity during degradation process were evaluated.
