Azine

Azines are a functional class of organic compounds with the connectivity RR'C=N-N=CRR'.

These compounds are the product of the condensation of hydrazine with ketones and aldehydes, although in practice they are often made by alternative routes.

[3] In the laboratory, azines are typically prepared by condensation of hydrazine with two equivalents of a carbonyl.

This method is used to determine trace levels of hydrazine in drinking water[14] and pharmaceuticals.

[15] Ketazines are also important intermediates in the industrial production of hydrazine hydrate by the peroxide process.
