2-Benzothiazolamine Usage And Synthesis
  • Chemical PropertiesBEIGE TO GREYISH POWDER OR FLAKES
  • UsesAn impurity of pramipexole production
  • General DescriptionOdorless gray to white powder.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity ProfileAn amine, organosulfide. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
  • Fire HazardFlash point data for 2-Benzothiazolamine are not available; however, 2-Benzothiazolamine is probably combustible.
  • Purification MethodsThe thiazole cystallises from a H2O, aqueous EtOH, *C6H6 or pet ether. The hydrochloride crystallises from dilute HCl and has m 240.5o. [Beilstein 27 H 182, 27 III/IV 4824.]
