| Hazard Information | Back Directory | [Chemical Properties]
Bluish-red powder. Soluble in water, slightly soluble in ethanol and acetone. Its aqueous solution is yellow to brownish red, turning reddish orange with dilute sulfuric acid and bright red with concentrated caustic soda. It is rose red in concentrated sulfuric acid, turning orange upon dilution, and disappears in concentrated nitric acid. Its color changes when it comes into contact with copper or iron during dyeing. | [Uses]
Mordant Red 7 is mainly used for dyeing and printing wool, silk and their fabrics, and can also dye nylon and its blended fabrics. The color of wool dyed products will change when exposed to ultraviolet light; those dyed by post-mortem will turn dark purple, while those dyed by pre-mortem will turn wine red. It is also used as a complexation indicator to determine calcium, copper, manganese, nickel, lead and zinc, as well as for fluorescent determination of fluorine, colorimetric determination of cobalt and gallium, and as a biological staining agent. | [Preparation]
4-Amino-3-hydroxynaphthalene-1-sulfonic acid diazotization, with 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one coupling. | [Properties and Applications]
blue light red. Blue light red powder. Soluble in water for yellow to brown light red, slightly soluble in ethanol and Acetone, insoluble in other organic solvent. In concentrated sulfuric acid for magenta, dilution after orange; In concentrated nitric acid for orange solution. Dye aqueous solution and 10% sulfuric acid as red orange; With strong caustic a cheery red or bright red. Used for wool fabric dyeing, dyeing scattered hair, tops, blankets and wool fabric, also can be dyed silk, polyamide fiber and its blended fabric. Can be in wool and silk fabric direct printing.
