靛酚反应是有机化学中一个重要的颜色反应，对硝基苯酚或其同系物在碱性条件下能和邻甲酚作用生成蓝色的靛酚。在常规毒物分析中，只有有机磷农药中的1605、甲基1605和杀螟松水解后能产生对硝基苯酚或其同系物，因此，它们能发生能酚反应。这对缩小检验范围，快速检出毒物具有 Indophenol reaction is an important color reaction in organic chemistry. P-nitrophenol or its homologues can react with o-cresol under alkaline conditions to produce blue indophenol. In the conventional analysis of toxicants, only p-nitrophenol or its homologues can be produced after hydrolysis of 1605, methyl-1605 and fenitrothion in organophosphorus pesticides, and therefore, they can react with phenol. This is to narrow the scope of testing, rapid detection of toxic substances
