| Hazard Information | Back Directory | [Chemical Properties]
Red powder. Solubility in water is 60g/L at 20°C and 100g/L at 50°C. The aqueous solution is red, and remains red even after adding 1mol/L sodium hydroxide. Adding hydrosulfite and warming turns the solution light yellow, but adding sodium perborate does not restore the solution to its original color. It is red in concentrated sulfuric acid and remains red after dilution, with a slight precipitate. It is red in concentrated nitric acid and remains red after dilution. It is red in dilute hydrochloric acid. | [Uses]
Reactive red 24 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-Amino-5-hydroxynaphthalene-2,7-disulfonic acidand 2,4,6-Trichloro-1,3,5-triazine condensation, 2-Aminobenzenesulfonic acid diazo, coupled with condensation products, and then and N-methylbenzenamine condensation and salting-out. | [Flammability and Explosibility]
Notclassified | [Properties and Applications]
blu-ray red. Red powder. The strong sulfuric acid for red, diluted is still red, and with a small amount of precipitation; In nitric acid for red, diluted in red. The dye solution for red, with 1 Moore sodium hydroxide solution is still red, continue to join insurance powder and warm, for light yellow, add a boric acid sodium is also can’t restore the original colour and lustre. Can be used for cotton or viscose fiber disseminated, roll dye, knot dyeing piled up dyeing. Can also be used to cotton or viscose fabric, the dye printing directly.
