FLAVIANIC ACID Chemical Properties,Uses,Production
Uses
FLAVIANIC ACID is used as an intermediate in organic synthesis, a precipitant for organic bases, and a reagent for amino acids. This product can react with more than 50 metal ions, but in acidic solutions it only precipitates with zirconium and lead, making it highly selective and sensitive for the determination of zirconium.
Definition
ChEBI: A naphthalenesulfonic acid that is naphthalene-2-sulfonic acid substituted by nitro groups at positions 5 and 7 as well as a hydroxy group at position 8. The disodium salt is the biological stain 'naphthol yellow S'.
