AURINTRICARBOXYLIC ACID Chemical Properties,Usage,Production

Chemical Properties

deep red coarse crystalline powder

Uses

endonuclease inhibitor; apoptosis inhibitor, topoisomerase II inhibitor

Definition

ChEBI: A member of the class of quinomethanes that is 3-methylidene-6-oxocyclohexa-1,4-diene-1-carboxylic acid in which the methylidene hydrogens are replaced by 4-carboxy-3-hydroxyphenyl groups. The trisodium salt is the biological stain 'chrome violet CG' while the triammonium salt is 'aluminon'.

Purification Methods

The acid is dissolved in aqueous NaOH, NaHSO3 solution is added until the colour is discharged and then the tricarboxylic acid is precipitated with HCl. [Heisig & Lauer Org Synth Coll Vol I 54 1941, Beilstein 10 IV 4161]. Do not extract the acid with hot water because it softens, forming a viscous mass. Make a solution in aqueous NH3. Aluminon is the NH4 salt.
