| Hazard Information | Back Directory | [Chemical Properties]
Purple-brown powder. Solubility in water (50°C) is 100g/L. The aqueous solution is reddish-purple. Addition of 1 mol/L sodium hydroxide solution remains reddish-purple. Addition of hydrosulfite and warming turns it colorless. Addition of sodium perborate does not restore the original color. In concentrated sulfuric acid, it is bluish-red, and upon dilution, it becomes rose-red. In concentrated nitric acid, it is orange-red, and upon dilution, it becomes light reddish-brown. | [Uses]
Reactive Violet 5 is an azo textile dye used in the textile and fabrics and paper-printing industries. | [Preparation]
2-(4-Aminophenylsulfonyl)ethyl hydrogen sulfate diazo, and 4-Aminonaphthalene-1-sulfonic acid coupling, and copper sulfate, sodium acetate and hydrogen peroxide oxidation, complex, then salting-out. | [Properties and Applications]
purple. Purple, brown powder, soluble in water. Used for cotton, silk and linen dyeing and printing, also suitable for discharge printing.
