Carbazide

In chemistry, a carbazide is a functional group with the general formula. They can be derived from the condensation of carbonic acid with a hydrazine. Carbohydrazide is the simplest carbazide, with another common carbazide being diphenylcarbazide, which is used as an analytical reagent.

Thiocarbazide

The sulfur analog is called a thiocarbazide, of which thiocarbohydrazide is the simplest example.

Carbazone and thiocarbazone

A carbazone is a partially oxidized carbazide with the general formula. The sulfur analog is called a thiocarbazone, of which dithizone is an example.
