| Description | Disperse yellow 3 is an azoic dye responsible for occupational contact dermatitis in workers in the textile industry. It can be found in some semipermanent hair dyes. |
| Uses | Disperse yellow 3 is used in dyeing textiles, sheepskins and furs; in coloring polymethyl methacrylate and nylon; in the surface dyeing of cellulose acetate; stocking dye. |
| Uses | Disperse Yellow 3 is an azo disperse dye which is water insoluble. Disperse Yellow 3 can be used to dye polyester and acetate fibers. Dyes and metabolites, Environmental Testing. |
| Preparation | N-(4-aminophenyl)acetamide diazo, and to a p-Cresol?coupling |
| Definition | ChEBI: An azo dye with a structure consisting of acetanilide substituted on the 4-position of the phenyl group with a 6-hydroxy-m-tolylazo group. |
| General Description | Brownish-yellow powder. |
| Air & Water Reactions | Azo dyes can be explosive when suspended in air at certain concentrations. Insoluble in water. |
| Reactivity Profile | Disperse Yellow 3 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Disperse Yellow 3 is incompatible with strong oxidizing agents and strong acids . |
| Fire Hazard | Flash point data for Disperse Yellow 3 are not available; however, Disperse Yellow 3 is probably combustible. |
| Contact allergens | This azoic dye is responsible for textile dermatitis from stockings and occupational contact dermatitis in workers in the textile industry. It can be found in some semipermanent hair dyes. |
| Safety Profile | Suspected carcinogen with experimental tumorigenic and carcinogenic data. Low toxicity by intraperitoneal route. An allergen. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx,. |
| Properties and Applications | Yellow powder soluble in ethanol acetone and benzene in strong sulfuric acid for orange diluted for gold?Yellow to yellow brown in the thick of sodium hydroxide solution for orange for polyester and its blending The fabric dyeing can also be used to vinegar fiber dyeing nylon and is fit for printing can also use?In such and plastic color
