| | Mordant Blue 29 Usage And Synthesis |
| Chemical Properties | dark brown powder | | Uses | Chromeazurol S (cas# 1667-99-8) is a compound useful in organic synthesis.Dyes and metabolites. | | Preparation | 2,4-Dichloro-3-formylbenzenesulfonic acid?and 2-Hydroxy-3-methylbenzoic acid condensation, its product oxidation and changed into sodium salt. | | Purification Methods | The crude phenolic triphenylmethanecarboxysulfonic acid triNa salt (40g) is dissolved in water (250mL) and filtered. Then conc HCl (50mL) is added to the filtrate, with stirring. The precipitate is filtered off, washed with HCl (2M) and dried. It is redissolved in water (250mL), and precipitation is repeated twice more in a water bath at 70o. It is dried under vacuum over solid KOH (first), then P2O5 [Martynov et al. Zh Analyt Khim 32 519 1977]. It has also been purified by paper chromatography using n-butanol, acetic acid and water (7:3:1). First and second spots were extracted. It chelates Al and Be. It is used also for estimating fluoride. [Beilstein 11 IV 707.] | | Properties and Applications | red light blue. Soluble in water for brown light yellow, slightly soluble in ethanol for red light brown. In concentrated sulfuric acid for hot magenta, after dilution to orange, and then generate a orange precipitation. Dye aqueous solution and sodium hydroxide as 3H-indol-3-one,2-(1,3-dihydro-3-oxo-2H-indol-2-ylidene)-1,2-dihydro- blue.
