light yellow powder | [Definition]
ChEBI: An organic sodium salt that is the disodium salt of 5,7-dinitro-8-hydroxynaphthalene-2-sulfonic acid. | [Uses]
Dye for wool, silk. | [Preparation]
4-Hydroxynaphthalene-1,3,6-trisulfonic acid or 1-Naphthol-4,7-disulfonic acid?or 1-Naphthol-2,7-disulfonic acid?or more of the latter with the nitro compounds and nitric acid reaction. | [Biological Activity]
Naphthol yellow S (NYS) is used as a stain for protein basic groups. It is an acidic dye and forms a NYS-protein complex at acidic pH. Combination of feulgen and NYS provides DNA to protein ratio. | [Properties and Applications]
colourful green light yellow. Soluble in cold water and hot water yellow, in 0 ℃ when solubility of 8%, slightly soluble in alcohol. Meet strong sulfuric acid is green light yellow, diluted colored light become weak. Its water solution to join sodium hydroxide have floc; Join chloride-ferric chloride solution from yellow to become yellow light brown. Apply to wool, polyamide fiber dyeing, coloured paper colourful yellow, the heavy metal salt can be used for printing ink and rubber color. Can also be used for soap, drug, cosmetics, biological and leather dyeing.

| [Purification Methods]
It is a water-soluble greenish yellow powder. The free sulfonic acid can be recrystallised from dilute HCl (m 150o) or AcOH/EtOAc (m 148-149.5o). The disodium salt is then obtained by dissolving the acid in two equivalents of aqueous NaOH and evaporating to dryness and drying the residue in a vacuum desiccator. The sodium salt can be recrystallised from the minimum volume of H2O or from EtOH [Dermer & Dermer J Am Chem Soc 61 3302 1939]. [Beilstein 11 III 542.] |
