Osazone formation was developed by Emil Fischer, [3] who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. [4] Since the reaction requires a free carbonyl group, only "reducing sugars" participate.
Structure of the hydrazone functional group. Hydrazones are a class of organic compounds with the structure R 1 R 2 C=N−NH 2. [1] They are related to ketones and aldehydes by the replacement of the oxygen =O with the = N−NH 2 functional group.

The Hinsberg reaction is a chemical test for the detection of primary, secondary and tertiary amines.The reaction was first described by Oscar Hinsberg in 1890. [1] [2] In this test, the amine is shaken well with the Hinsberg reagent (benzenesulfonyl chloride) in the presence of aqueous alkali (either KOH or NaOH).
