The Uses of XANTHURENIC ACID

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.

The Uses of XANTHURENIC ACID

Purification Methods

It is precipitated by the addition of 2N formic acid to its solution in hot 2M ammonia (charcoal). The solid is filtered off, dried in a vacuum at ~80o in the dark. UV (H2O) has nm ( M-1cm-1): 243 (30,000) and 342 (6,500). The methyl ester has m 262o (from MeOH). It forms Cu2+, Zn2+, Fe2+ and Fe3+ salts. [Beilstein 22 III/IV 2513.]
