CHICAGO SKY BLUE 6B Usage And Synthesis
  • Chemical Propertiesgreenish blue powder
  • UsesCompetitive glutamate uptake inhibitor
  • General DescriptionBright greenish-blue solid or dark blue powder.
  • Air & Water ReactionsAzo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water.
  • Reactivity ProfileCHICAGO SKY BLUE 6B 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. Cleavage of the diazo group by reducing agents may lead to benzidine production.
  • Fire HazardFlash point data for CHICAGO SKY BLUE 6B are not available; however, CHICAGO SKY BLUE 6B is probably combustible.
  • Biological ActivityPotent inhibitor of L-glutamate uptake into synaptic vesicles.
  • Safety ProfileAn experimental teratogen. Other experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx Na2O, and SOx
  • Purification MethodsFree it from other electrolytes by adding aqueous sodium acetate to a boiling solution of the dye in distilled water. After standing, the salted-out dye is filtered on a Büchner funnel, the process being repeated several times. Finally, the precipitated dye is boiled several times with absolute EtOH to wash out any sodium acetate, then dried (as the sodium salt) at 105o. [McGregor et al. Trans Faraday Soc 58 1045 1962, Beilstein 16 II 259.]
