Diphenylcarbazide

In chemistry, a carbazide is a functional group with the general formula RNH-NH(C=O)NH-NHR. 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.[1] The sulfur analog is called a thiocarbazide, of which thiocarbohydrazide is the simplest example.

Carbazone

A carbazone is partially oxidised carbazine with the general formula R=NNH(C=O)NH-NHR. The sulphur analogue is called a thiocarbazone, of which dithizone is an example.
