- Box
Bial's reagent consists of 0.4 g orcinol, 200 ml of concentrated hydrochloric acid and 0.5 ml of a 10% solution of ferric chloride. Bial's test is used to distinguish pentoses from hexoses; this distinction is based on the color that develops in the presence of orcinol and iron (III) chloride.
Bial's test is a chemical test for the presence of pentoses. It is named after Manfred Bial, a German physician. The components include orcinol, hydrochloric acid, and ferric chloride. A pentose, if present, will be dehydrated to form furfural which then reacts with the orcinol to generate a colored substance.
Application
Bial's Reagent: 300 mg of orcinol is dissolved in 5 ml ethanol. Add 3.5 ml of this mixture to 100ml of 0.1% solution of FeCL3. 6H2O. The reagent thus formed is to be stored in a dark bottle and used within a couple of hours.
