2-[2-HYDROXY-3-(2,4-XYLYLCARBAMOYL)-1-NAPHTHYLAZO]PHENOL Chemical Properties,Usage,Production

Purification Methods

Suspend it in H2O and add aqueous NaOH until it dissolves, filter and acidify with dilute HCl. Collect the dye, dissolve it in hot EtOH (solubility is 100mg/L at ca 25o) concentrate to a small volume and allow to cool. The solubility of the Na salt in H2O is 0.4mg/mL.
