2-Mercapto-5-nitrobenzimidazole is a nitro-substituted benzimidazole derivative with versatile applications in pharmaceutical synthesis and material science. This compound exhibits a melting point of 274°C (dec.) and predicted boiling point of 348.4±44.0°C. With a density of 1.4666 g/cm³ (estimate) and solubility in 1M NaOH (50 mg/mL), it serves as a key intermediate for proton pump inhibitors like ilaprazole (as impurity 84). The material should be stored at -20°C under inert atmosphere due to its sensitivity. Safety precautions include wearing protective equipment as it may cause skin/eye irritation (GHS Category 2). Its unique structure enables applications in organic electronics, particularly for modifying electrode surfaces in thin-film transistors.
