The study demonstrated characteristic shape of osazone of sugars by performing osazone … Osazone formation was developed by Emil Fischer, who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. Since the reaction requires a free carbonyl group, only "reducing sugars" participate. Sucrose, which … See more Osazones are a class of carbohydrate derivatives found in organic chemistry formed when reducing sugars are reacted with excess of phenylhydrazine at boiling temperatures. See more Osazones are highly coloured and crystalline compounds. Osazones are readily distinguished. • Maltosazone (from maltose) forms petal-shaped crystals. • Lactosazone (from lactose) forms powder puff-shaped crystals. See more • Fischer, Emil (1908).

See more WebThe osazone reaction was developed and used by Emil Fischer to identify aldose sugars differing in configuration only at the alpha-carbon. The upper equation shows the general form of the osazone reaction, which effects an alpha-carbon oxidation with formation of a bis-phenylhydrazone, known as an osazone. john stahl public library west point nebraska
