Safety Information
Basic Red 9 Usage And Synthesis
  • Chemical Propertiesgreen crystalline powder
  • Chemical PropertiesC.I. Basic red 9 is a colorless to red crystalline solid or green powder.
  • UsesAntischistosoma.
  • DefinitionChEBI: A hydrochloride that is the monohydrochloride of 4,4'-[(4-iminocyclohexa-2,5-dien-1-ylidene)methanediyl]dianiline. One of the major constituents of Basic fuchsin, together with rosanilin, magenta II and new fuchsin.
  • General DescriptionColorless to red crystals or green powder.
  • Air & Water ReactionsInsoluble in water.
  • Health HazardACUTE/CHRONIC HAZARDS: When heated to decomposition Basic Red 9 emits very toxic fumes of hydrogen chloride and nitrogen oxides.
  • Fire HazardFlash point data for Basic Red 9 are not available; however, Basic Red 9 is probably combustible.
  • Safety ProfileConfirmed carcinogen with experimental carcinogenic and tumorigenic data. Mildly toxic by ingestion. Mutation data reported. When heated to decomposition it emits very toxic fumes of HCl and NOx.
  • Potential ExposureUsed as a dye for textiles, paper; printing, computer and photo imaging inks, leather, and many consumer products; as a microbiological/microscopy stain for bacilli, including tubercle and influenza.
  • CarcinogenicityBasic red 9 monohydrochloride is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity fromstudies in experimental animals.
  • ShippingUN 3143 Dyes, solid, toxic, n.o.s., or dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1—Poisonous materials, Technical Name Required.
  • IncompatibilitiesMay be combustible; powder or liquid may form explosive mixture with air. 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.
  • Waste DisposalUse a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
