| [Definition]
ChEBI: Chromone-3-carboxylic acid is a member of chromones. | [Synthesis Reference(s)]
Synthetic Communications, 10, p. 889, 1980 DOI: 10.1080/00397918008061846 | [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. |
