ACID RED 26 Chemical Properties,Usage,Production

Chemical Properties

dark red to bordeaux fine powder

Uses

A stain used in histology and in Masson’s trichrome stain.

Uses

Acid Red 26 is an acid azo red dye used in inks and fabrics. Contributor to environmental pollution and textile effluents. Dyes and metabolites, Environmental Testing.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list.

Preparation

2,4-Dimethylbenzenamine diazo, coupled with 3-Hydroxynaphthalene-2,7-disulfonic acid.

Definition

ChEBI: An organic sodium salt that is the disodium salt of 4-[(2,4-dimethylphenyl)diazenyl]-3-hydroxynaphthalene-2,7-disulfonic acid. Its use is largely confined to Masson's trichrome, where it gives a slight orange shading to the red of the cytoplasmic structure .

General Description

Dark red crystals or red powder.

Air & Water Reactions

Azo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water.

Reactivity Profile

ACID RED 26 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. ACID RED 26 is incompatible with strong oxidizing agents and strong acids .

Fire Hazard

Flash point data for ACID RED 26 are not available; however, ACID RED 26 is probably combustible.

Safety Profile

Moderately toxic by intraperitoneal route. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx and SOx.

Properties and Applications

colourful red yellow light. Soluble in water for red orange to red, hardly soluble in ethanol and acetone, insoluble in other organic solvents. The strong sulfuric acid are blushing to wine red, yellow and red for diluted. In water solution to join strong hydrochloric acid have red precipitate; Join nitric acid by bright red to orange; Add thick sodium hydroxide solution into orange brown; Add 10% sodium hydroxide solution for palm red.
