Industrially, dehydroacetic acid has several uses which include the following:
- a fungicide and bactericide. The sodium salt, sodium dehydroacetate, is often used in place of dehydroacetic acid because of its greater solubility in water.
- a food preservative to prevent pickle bloating in squash and strawberries. When used as a food additive, dehydroacetic acid is referred to using the International Numbering System for Food Additives or E number 265.
- a plasticizer in synthetic resins.
- an antienzyme in toothpastes.
- a precursor for dimethyl-4-pyridones. The compounds are synthesized when dehydroacetic acid is exposed to aqueous solutions containing primary amines.
