5-Nitrobenzimidazole Chemical Properties,Usage,Production

Chemical Properties

white or pale yellow powder

Uses

Antifogging agent in photographic developers.

Uses

5-Nitrobenzimidazole acts as a reagent in the synthesis of benzimidazoles derivatives with antibacterial and antifungal activities. It also functions as a reagent in the synthesis of xanthine oxidase, a key enzyme that catalyze xanthine to uric acid causing hyperuricemia in humans.

General Description

Off-white to pale yellow fluffy powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

5-Nitrobenzimidazole is incompatible with strong oxidizing agents and strong bases.

Fire Hazard

Flash point data for 5-Nitrobenzimidazole are not available but 5-Nitrobenzimidazole is probably combustible.

Synthesis

64-18-6

99-56-9

94-52-0

First, 4-nitrophthalimide (1 g) was mixed with formic acid (0.74 mL) in 5N hydrochloric acid (70 mL), stirred and heated to reflux for 24 hours. Upon completion of the reaction, the mixture was cooled to room temperature, neutralized with 10% sodium hydroxide solution and the precipitate was isolated. Subsequently, the precipitate was recrystallized with water and dried to give 5-nitrobenzimidazole (0.69 g) [37].
