二甲苯基蓝I钠盐(CAS号：14936-97-1)通常如何合成？
答案
![Sodium 3-[(E)-{3-[(2,4-dimethylphenyl)carbamoyl]-2-hydroxy-1-naphthyl}diazenyl]-4-hydroxybenzenesulfonate](https://cnstatic.chemtradehub.com/structs/149/14936-97-1-50cf.webp "Sodium 3-[(E)-{3-[(2,4-dimethylphenyl)carbamoyl]-2-hydroxy-1-naphthyl}diazenyl]-4-hydroxybenzenesulfonate")
二甲苯基蓝I钠盐的合成通常通过重氮化反应和偶联反应完成。首先，2,4-二甲基苯胺与亚硝酸钠反应生成重氮盐，然后该重氮盐与1-萘酚和NaHSO3发生偶联反应，最后通过中和生成钠盐。这个过程中需要严格控制反应温度和pH，以确保产物的产率和纯度。
