Uses
Direct Blue 218 is an azo dye used in diagnostic imaging. Used in the prediction of rat carcinogenisis. Also used in textile dyes contributing to textile effluents and wastewaters.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list.
Preparation
3,3′-Dimethoxylbenzidine double nitriding, in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid(2 Moore) coupling, and then will product into copper complex.
General Description
Deep purple to dark blue amorphous powder.
Air & Water Reactions
Water soluble. Azo dyes can be explosive when suspended in air at specific concentrations.
Reactivity Profile
tetrasodium [mu-[[3,3'-[(3,3'-dihydroxy[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[5-amino-4-hydroxynaphthalene-2,7-disulphonato]](8-)]]dicuprate(4-) is a diazo compound. Azo, diazo, azido compounds can detonate. The nitro groups would facilitate rapid decomposition. 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.
Fire Hazard
