Acetone hydrazone (isopropylidenehydrazine) is the product of condensation of acetone and hydrazine, as typical for hydrazone formation. It is an intermediate in the synthesis of 2-diazopropane [fr].[2]

Acetone hydrazone can be produced on large scale by reaction of acetone azine with hydrazine, a more convenient reaction than direct reaction of acetone and hydrazine.[3] Likewise, it is susceptible to disproportionation to revert to acetone azine and hydrazine, especially in the presence of water.[3]

The chemical is one of the metabolic products of the antihypertensive pharmaceutical hydralazine, and itself also have antihypertensive effects.[4]
