4- Hydroxybenzoylhydrazine ( PAHBAH ) reacts with glucose in hot aqueous solution when alkali exceeds aroylhydrazine concentration. The related 2- furoylhydrazine ( FAH ) reacts at lower alkali concentrations, making this an attractive alternative carbohydrate reagent since it is (unlike PAHBAH ) freely water soluble. FAH reacts with monosaccharides more slowly than does PAHBAH , giving about half the color. Its specificity and behavior with a bismuth catalyst parallel those of PAHBAH . Solutions which contain 0.05 mol/liter PAHBAH with 1.5 mmol/liter bismuth III (as tartrate complex) and 0.5 mol/liter sodium hydroxide, or 0.01 mol/liter FAH with 1.5 mmol/liter bismuth III and 0.1 mol/liter sodium hydroxide are sensitive reagents for quantitative analysis, giving stable colors with many carbohydrates within 10 min at 75 degrees C. Ketosamines react more rapidly than glucose at lower temperatures and undergo similar reactions in less alkaline solutions. At pH less than 8, the reaction is specific for these 1- aminohexoses , and FAH can be used as a reagent for their assay.
