C.I. Acid Yellow 25 (6359-85-9) |
| Hazard Information | Back Directory | [Chemical Properties]
Soluble in water. Slightly soluble in ethanol and acetone. Its aqueous solution is yellow and does not change color upon addition of sodium hydroxide; it becomes turbid upon cooling. It is yellow in concentrated sulfuric acid and produces a fluorescent yellow precipitate upon dilution. | [Uses]
Acid Yellow 25 is a stain/dye. Dyes and metabolites. | [Preparation]
5-Amino-2-methyl-N-phenylbenzenesulfonamide?diazo, and 4-(3-Methyl-5-oxo-4,5-dihydropyrazol-1-yl)benzenesulfonic acid coupling. | [Flammability and Explosibility]
Notclassified | [Properties and Applications]
yellow. Yellow powder. Soluble in water yellow, encounter cold becomes muddy. Slightly soluble in ethanol and acetone. Meet strong sulfuric acid is yellow, the generation after diluted fluorescent yellow precipitation. Its water solution meet sodium hydroxide solution without change. Mainly used for wool and polyamide fiber of printing and dyeing, also can be used for leather and electrochemical aluminum shading, occasionally used for paper coating.
