BENZOPURPURIN 4B Usage And Synthesis
Chemical Propertiesdark red or brown powder
UsesFor dyeing primarily cotton and viscose rayon: Colour Index vol. 2 (3rd ed., 1971) p 2101. As an analytical reagent in detection of Al, Mg, Hg, Ag, U; as a biological stain; as pH indicator, violet 1.2 to red 4.0.
General DescriptionBrown to dark red powder.
Air & Water ReactionsAzo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
Reactivity ProfileBENZOPURPURIN 4B 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.
Fire HazardFlash point data for BENZOPURPURIN 4B are not available. BENZOPURPURIN 4B is probably combustible.
Purification MethodsIt crystallises from H2O. It is a biological stain that is violet at pH 1.2 and red at pH 4.0 and is used for detecting Al, Mg, Hg, Au and U. [Beilstein 16 H 411, 16 II 224, 16 III 474, 16 IV 601.]
