Sodium 4-hydroxybenzenesulfonate Usage And Synthesis

Uses	4-Hydroxybenzenesulfonic Acid is a useful synthetic intermediate. It is used in the synthesis of difluoromethyl sulfonates. It can be also used to prepare Famphur Oxon (F102330) which is a metabolite of Famphur (F102325), an organophosphate insecticide and pesticide.
Flammability and Explosibility	Notclassified
Purification Methods	It crystallises from hot water (1mL/g) by cooling to 0o, or from MeOH, and is dried in vacuum. [Beilstein 11 II 134.]
