| | 2,5-dihydroxybenzenesulphonic acid Usage And Synthesis |
| Originator | Dicynone,Delalande,France,1965 | | Uses | Isopropyl Quinonesulfonate is a derivative of Sodium quinonesulfonate(51579-78-3), and an impurity of Calcium Dobesilate (C145100). | | Definition | ChEBI: A dihydroxybenzenesulfonic acid that is hydroquinone in which one of the phenyl hydrogens is substituted by a sulfonic acid group. | | Manufacturing Process | 163 grams of pure diethylamine bisulfite are added to an ethyl alcohol
solution of 108 grams of 1,4-benzoquinone at a temperature not above 5°C
and under continuous stirring. After reaction, the alcohol is removed by
distilling under vacuum. The product is recrystallized from ethyl alcohol at
80°C. Yield: 198 grams of diethylammonium cyclohexadienol 4-one-1-
sulfonate-4. MP 125°C. | | Therapeutic Function | Hemostatic |
