Description 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. Application Chromone-3-carboxylic acid may be used in the preparation of: • chromane-2,4-diones • chromone-3-carboxamides • 5-(2-hydroxyphenyl)isoxazole • chromone-2-carboxamides • chromone-2-carboxamido-3-esters Packaging 5 g in glass bottle
