What is 2 methyl 5-nitroimidazole used for?

FAQ 2025-04-07

  1. Pharmaceuticals:
    • Drug Intermediate: Serves as a critical precursor in the synthesis of antibiotics, antifungals, and antiparasitic agents. Notably, it is used to produce metronidazole (Flagyl®) and dimetridazole, drugs effective against anaerobic bacteria and protozoal infections such as amebiasis, trichomoniasis, and giardiasis.
    • Antimicrobial Activity: Exhibits inherent antimicrobial properties, making it valuable in formulations targeting bacterial and parasitic pathogens.
  2. Agriculture:
    • Pesticides and Fungicides: Employed in the manufacture of agricultural chemicals to enhance crop resistance to pests and diseases, thereby improving yield and quality.
  3. Materials Science:
    • Functional Monomer: Acts as a monomer in polymer synthesis, introducing specific properties (e.g., enhanced mechanical strength, chemical resistance) into polymeric materials for industrial and technological applications.

Physicochemical Properties:

  • Molecular Formula: C₄H₅N₃O₂
  • Molecular Weight: 127.10 g/mol
  • Melting Point: 252–254°C
  • Boiling Point: 399.5 ± 15.0°C (at 760 mmHg)
  • Density: 1.4 ± 0.1 g/cm³
