Answer
![Sodium 4-[3,6-bis(diethylamino)-9-xantheniumyl]-1,3-benzenedisulfonate](https://static.chemtradehub.com/structs/352/3520-42-1-eb28.webp "Sodium 4-[3,6-bis(diethylamino)-9-xantheniumyl]-1,3-benzenedisulfonate")
Sodium 4-[3,6-bis(diethylamino)-9-xantheniumyl]-1,3-benzenedisulfonate is synthesized through a multi-step process involving the condensation of xanthenyl derivatives with benzenedisulfonic acid. Commonly, this involves the use of concentrated sulfuric acid as a catalyst to enhance the reaction yield. The process is highly selective, with a yield of about 85% under optimal conditions.
