基于商品化的普通色谱柱建立了2-(氟苯基)-5-甲基苯并恶唑和2-(氯苯基)-5-甲基苯并恶唑邻、间、对位置异构体的分离检测方法.色谱柱为Inertsil ODS-SP C18(250mnx4.6 mm,5μm),以乙腈(A)和水(B)为流动相,在60%A~80%A间线性梯度洗脱15 min,流速为1.5 mL/min,柱温40℃,检测波长为310 nm.在质量浓度为2~200 mg/L范围内,2-(氟苯基)-5-甲基苯并恶唑邻、间、对位的异构体、2-(氯苯基)-5-甲基苯并恶唑邻、间、对位的异构体具有良好的线性关系,6种化合物的检出限(S/N=3)依次为0.030 7、0.029 3、0.031 5、0.022 6、0.023 7、0.022 6 mg/L.该法既为5-甲基苯并恶唑与氟苯或氯苯碳氢活化偶联反应制备的异构体混合物提供了一个快速检测的方法,又为2-芳基苯并恶唑类异构体的分离检测提供了参考.
