Direct Blue 14 Usage And Synthesis

Chemical Properties

blueish grey powder

Chemical Properties

Trypan Blue is a dark Blue crystalline solid or powder.

Uses

Biological stain.

Definition

ChEBI: An organosulfonate salt that is the tetrasodium salt of 3,3'-[(3,3'-dimethylbiphenyl-4,4'-diyl)didiazene-2,1-diyl]bis(5-amino-4-hydroxynaphthalene-2,7-disulfonic acid).

General Description

Bluish-gray to dark blue powder.

Air & Water Reactions

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

Reactivity Profile

Direct Blue 14 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. Direct Blue 14 is incompatible with strong oxidizing agents and strong acids.

Health Hazard

ACUTE/CHRONIC HAZARDS: Direct Blue 14 may cause irritation and may be absorbed through the skin. It is a positive animal carcinogen. When heated to decomposition Direct Blue 14 emits very toxic fumes of nitrogen oxides, sulfur oxides, carbon monoxide and carbon dioxide.

Fire Hazard

Flash point data for Direct Blue 14 are not available; however, Direct Blue 14 is probably combustible.

Safety Profile

Suspected carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by intraperitoneal, intravenous, and subcutaneous routes. Experimental teratogenic and reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx NazO, and SOx

Potential Exposure

Used in dyeing textiles; leather and paper; as a biological stain.

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3143 dyes, solid, toxic, n.o.s. or dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Dust may form explosive mixture with air. Trypan Blue is incompatible with strong oxidizing agents. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Azo 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, acylhalides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combinations can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Trypan Blue is sensitive to prolonged exposure to heat.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
