Dehydroacetic acid Uses

Methylacetopyronone (CAS NO.520-45-6) is a pyrone derivative used as a fungicide and bactericide. It is used to reduce pickle bloating as a preservative for squash and strawberries. The sodium salt, sodium dehydroacetate, is often used in place of dehydroacetic acid because of its greater solubility in water. Industrially, it is also used as a plasticizer in a variety of synthetic resins.
