Chemical Properties

Trypan Blue is a dark Blue crystalline solid or powder.

Uses

Biological stain.

Uses

Trypan Blue is an azo based, hydrophilic, tetrasulfonated blue acid dye widely utilized for assessing cell viability. As an easy method to determining the viability of cells, Trypan Blue will stain dead cells with permeable membranes blue, while the dye is excluded by most living cells and their intact membranes thereby allowing visual determination of living versus dead cells. Although Trypan Blue is predominately used for assessing cell viability of cultured cells, other applications for this dye have been reported. In rat abdominal organ slices Trypan Blue has been utilized to determine cell viability as well as islet cell cluster cell viability from caprine pancreatic samples. Dyes and metabolites.

Uses

Trypan blue has been used as a dye in trypan blue exclusion assay/cell viability assay to detect dead cells.

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).

Preparation

3,3′-Dimethylbenzidine double nitriding, in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid(2 Moore) coupled.

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.

Biochem/physiol Actions

Trypan Blue is excluded by most living cells, but can be taken into phagocytes and certain other cells.

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.

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.
