Answer
![Sodium 4-[(E)-(4-hydroxy-1-naphthyl)diazenyl]benzenesulfonate](https://static.chemtradehub.com/structs/523/523-44-4-5476.webp "Sodium 4-[(E)-(4-hydroxy-1-naphthyl)diazenyl]benzenesulfonate")
Sodium 4-[(E)-(4-hydroxy-1-naphthyl)diazenyl]benzenesulfonate is typically synthesized via a diazotization reaction of 4-nitrobenzenesulfonic acid with 4-hydroxy-1-naphthylamine followed by reduction to the azide. The process requires careful control of pH and temperature to achieve high yield and selectivity.
