Chromone (or 1,4-benzopyrone) is a derivative of benzopyran with a substituted keto group on the pyran ring. It is an isomer of coumarin.

Derivatives of chromone are collectively known as chromones. Most, though not all, chromones are also phenylpropanoids.

Examples[edit]

  • Nedocromil sodium was found to have a somewhat longer half-life than cromolyn; however, production was discontinued in the US in 2008.
