| Hazard Information | Back Directory | [Chemical Properties]
It dissolves in water to a reddish-purple color, is soluble in ethylene glycol ether, is slightly soluble in ethanol, and is insoluble in other organic solvents. Adding concentrated hydrochloric acid to its aqueous solution produces a purple precipitate; adding concentrated sodium hydroxide solution also produces a purple precipitate. The dye exhibits a bluish-green color in concentrated sulfuric acid and a purple precipitate upon dilution. It produces a reddish-brown solution in concentrated nitric acid. | [Uses]
C.I. Direct Violet 9 is a multifunctional dye. Dyes are important tools in biological experiments. They can help researchers observe and analyze cell structures, track biomolecules, evaluate cell functions, distinguish cell types, detect biomolecules, study tissue pathology and monitor microorganisms. Their applications range from basic scientific research to clinical A wide range of diagnostics. Dyes are also widely used in traditional fields such as textile dyeing, as well as in emerging fields such as functional textile processing, food pigments and dye-sensitized solar cells. | [Preparation]
4-Aminobenzenesulfonic acid diazo, and 2-Amino-4-methylanisole coupling, its product to diazo, in alkaline conditions and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid coupling. | [Flammability and Explosibility]
Nonflammable | [Properties and Applications]
blue purple. Soluble in water for red light purple, soluble in soluble fiber element, slightly soluble in alcohol, insoluble in other organic solvents. The strong sulfuric acid for blue-ray green, purple precipitation after diluted; In nitric acid solution for the red light in brown. The dye solution to the strong hydrochloric acid has the purple precipitation; Add thick sodium hydroxide solution has the purple sediment: cotton, viscose, silk dyeing and printing, also can be used for paper color, can also be used in leather color.
