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).

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. Likewise, it is susceptible to disproportionation to revert to acetone azine and hydrazine, especially in the presence of water.

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