| Hazard Information | Back Directory | [General Description]
Plates (in water); white powder. | [Reactivity Profile]
2-AMINOBENZIMIDAZOLE(934-32-7) neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. | [Air & Water Reactions]
Insoluble in water. | [Health Hazard]
ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of nitrogen oxides. | [Fire Hazard]
Flash point data for this chemical are not available; however, 2-AMINOBENZIMIDAZOLE is probably combustible. | [Chemical Properties]
light yellow to cream or beige powder or flakes | [Uses]
2-Aminobenzimidazole was used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles. | [Uses]
2-Aminobenzimidazole was used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles | [Definition]
ChEBI: A member of the class of benzimidazoles that is benzimidazole in which the hydrogen at position 2 is replaced by an amino group. | [Preparation]
Synthesis of 2-aminobenzimidazole: Cyanogen bromide (3.5 g., 0.034 mole) was added in small portions, with shaking, to a suspension of o-phenylenediamine (4.2 g. , 0.34 mole) in water (40 ml), the exothermic reaction mixture was cooled to room temperature and it was stirred for 36hrs. The solution was filtered after standing overnight. Sodium hydroxide (1.4 g., 0.034 mole) in 30 ml of water was then added and the solution was evaporated. The solid thus obtained was filtered and recrystalized from water. Yield 85%, m.p. 228 - 230°C |
