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.

Hydrazones are converted to azines when used in the preparation of 3,5-disubstituted 1H-pyrazoles, [12] a reaction also well known using hydrazine hydrate. [13] [14] With a transition metal catalyst, hydrazones can serve as organometallic reagent surrogates to react with various electrophiles. [15]
Reagent testing is one of the processes used to identify substances contained within a pill, usually illicit substances. With the increased prevalence of drugs being available in their pure forms, the terms "drug checking" or "pill testing" [1] may also be used, although these terms usually refer to testing with a wider variety of techniques covered by drug checking.
