Is an organic compound that famously exists in two tautomeric forms that rapidly interconvert. It is a colourless liquid that is a precursor to acetyl acetonate (acac), a common bidentate ligand. One of the most common applications of Acetyl Acetone is its usage in the production of coatings and anti-corrosion agents. Acetyl Acetone acts as a pot-life extender in coating applications which extends the curing time of the dry. Another common usage of Acetyl Acetone (2,4-Pentanedione) is as a radical initiator in peroxide compounds to induce polymerization. Acetyl Acetone is also an important intermediate used in organic synthesis as a building block for heterocyclic compounds.
