2832-40-8 Usage

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

Different sources of media describe the Uses of 2832-40-8 differently. You can refer to the following data:
1. 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.
2. 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.

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,.

Check Digit Verification of cas no

The CAS Registry Mumber 2832-40-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,3 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2832-40:
(6*2)+(5*8)+(4*3)+(3*2)+(2*4)+(1*0)=78
78 % 10 = 8
So 2832-40-8 is a valid CAS Registry Number.

Acid Dissociation Constants of Some 2-Hydroxy-5-methyl-4-Substituted-azobenzenes and Formation Constants of Their Chelates with Iron(III), Cobalt(II), Nickel(II) and Copper(II)

Masoud, Mamdouh S.,Osman, M. M.,Salem, T. M.,Khalil, E. A.

, p. 584 - 587 (2007/10/02)

Acid dissociation constants, pKa, are reported for a set of 2-hydroxy-5-methyl-4-substituted azobenzenes in 50percent (v/v) ethanol medium at 25+/-0.1 deg C and μ = 0.1.The substituent and the solvent, beside the pH are found to affect the tautomeric phenomena in the ligands.The ligands form 1:1 and 1:2 complexes in solutions.The pK values of the complexes have been evaluated spectrophotometrically.The complexes have been isolated in the solid state and characterized on the basis of elemental analyses, infrared and electronic spectral data.The solid complexes exist in the octahedral spatial configuration.
