Direct Blue 53 Chemical Properties,Usage,Production

Chemical Properties

brownish crystalline powder

Uses

antineoplastic

Definition

ChEBI: An organic sodium salt that is the tetrasodium salt of 6,6'-{(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis[diazene-2,1-diyl]}bis(4-amino-5-hydroxynaphthalene-1,3-disulfonate). It is sometimes used as a counterstain, especially in fluorescent methods to suppr ss background autofluorescence.

Preparation

3,3′-Dimethylbenzidine double nitriding, in alkaline conditions and 4-Amino-5-hydroxynaphthalene-1,3-disulfonic acid (2 Moore) coupled.

General Description

Blue crystals with a greenish-bronze luster or a black powder.

Air & Water Reactions

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

Reactivity Profile

Direct Blue 53 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 53 can react with strong reducing and oxidizing agents.

Fire Hazard

Flash point data for Direct Blue 53 are unavailable; however, Direct Blue 53 is probably combustible.

Biological Activity

Potent inhibitor of L-glutamate uptake into synaptic vesicles. Also inhibits AMPA and kainate receptor-mediated currents (IC 50 values are 220 and 150 nM respectively). P2X-selective purinoceptor antagonist.

Safety Profile

Poison by intraperitoneal route.Moderately toxic by intravenous route. An experimentalteratogen. Other experimental reproductive effects.Questionable carcinogen with experimental tumorigenicdata. Mutation data reported. When heated todecomposition it

Properties and Applications

dark green light blue. Soluble in water for bright blue. The strong sulfuric acid for blue-ray green, diluted for light yellow. The dye solution to join hydrochloric acid as bright blue; Add sodium hydroxide solution for the purple and red.
