Application

Xanthurenic acid can be used as a substrate for the synthesis of:
  • Silica-gel functionalized xanthurenic acid (4, 8-dihydroxyquinoline-2-carboxylic acid) as an adsorbent for metal ions.
  • N, N′-bis-((8-hydroxy-7-quinolinyl)methyl)-1,10-diaza-18-crown-6 ethers as fluorescent sensors of magnesium in living cells via one-pot Mannich reaction.
  • Poly-xanthurenic acid (poly-Xa) for biosensing applications.
