General description

Chromone-3-carboxylic acid is a chromone derivative. Its potential as an antioxidant in charge transfer (CT) processes has been assessed by surface-enhanced Raman scattering (SERS) analysis of chromone 3-carboxylic acid adsorbed on silver colloids.[1]

Application

Chromone-3-carboxylic acid may be used in the preparation of:
  • chromane-2,4-diones
  • chromone-3-carboxamides
  • 5-(2-hydroxyphenyl)isoxazole[2]
  • chromone-2-carboxamides[1]
  • chromone-2-carboxamido-3-esters[1]
