Barfoed’s Test: Barfoed’s reagent, cupric acetate in acetic acid, is marginally acidic and is stableso that it can only be abridged by monosaccharides but not less potent reducing sugars. Disaccharides may also react with this reagent, but the feedback is muchslower when compared to monosaccharides.
