Anthranilic acid Chemical Properties,Usage,Production

  • Chemical Properties White to off white crystalline powder
  • Uses Dyes, drugs, perfumes, and pharmaceuticals.
  • Definition ChEBI: An aminobenzoic acid that is benzoic acid having a single amino substituent located at position 2. It is a metabolite produced in L-tryptophan-kynurenine pathway in the central nervous system.
  • General Description Odorless white to pale-yellow or tan crystalline powder with a sweetish taste.
  • Air & Water Reactions Anthranilic acid may be sensitive to prolonged exposure to air and light. Insoluble in water.
  • Reactivity Profile Anthranilic acid is incompatible with strong oxidizers.
  • Hazard Questionable carcinogen.
  • Fire Hazard Anthranilic acid is combustible.
  • Safety Profile Moderately toxic by ingestion and intraperitoneal routes. Experimental reproductive effects. Human mutation data reported. Questionable carcinogen with experimental tumorigenic data. Combustible. When heated to decomposition it emits toxic fumes of NOx.
  • Purification Methods Crystallise anthranilic acid from water (charcoal). It has also been recrystallised from 50% aqueous acetic acid. It sublimes in a vacuum. [Beilstein 14 IV 1004.]
