ACID ALIZARIN VIOLET N Usage And Synthesis

Chemical Properties

red powder

Purification Methods

Convert the acid to the monosodium salt by precipitation with NaOAc/AcOH buffer of pH 4, then purify by precipitation of the free acid from aqueous solution with conc HCl, washing and extracting with EtOH in a Soxhlet extractor. The acid precipitates on evaporating the EtOH and is reconverted to the sodium salt as described for Chlorazole Sky Blue FF. Dry it at 110o. It is hygroscopic.
