摘要
农药中的杂质,特别是相关杂质,常常对农药产品的品质造成不良影响,并增加农药产品的使用风险。本文概述了农药原药中杂质的一般分析流程,并解析了杂质的主要来源。并详细分类介绍了主要相关杂质的类型及主要特征官能团,阐述了胺类化合物的主要化学衍生化反应类型,进一步引出了稳定同位素同时标记的化学衍生化方法在杂质识别过程中独特作用。论文相关内容有利于增强对农药杂质分子特性的了解,并为提升农药相关杂质的识别和解析提供有价值的参考。
Pesticide impurities,particularly relevant impurities,have a detrimental impact on the quality of pesticide products and increase pesticide usage risks.This article outlines the general analysis process for pesticide impurities and summarizes the potential sources of impurities.It provides a detailed classification of major relevant impurities and their characteristic functional groups.The major chemical derivatization reaction types of amine compounds and stable isotope labeling chemical derivatization methods are introduced.This article is conducive to enhancing the understanding of the molecular characteristics of pesticide impurities,and provides valuable reference for improving the identification and analysis of pesticides impurities.
