  FUCTION AND APPLICATION

  
  

  Chemical properties: 

  Imidazole is a five-membered aromatic heterocyclic compound containing two intermediate nitrogen atoms in the molecular structure. The unshared electron pairs of 1-position nitrogen atoms in the imidazole ring participate in ring conjugation, and the electron density of nitrogen atoms decreases, so that the hydrogen on this nitrogen atom is easy to leave in the form of hydrogen ions. 

  Therefore, imidazole is weakly acidic and can form salts with strong bases. The unshared electron pairs of the 3-position nitrogen atoms in the imidazole ring do not participate in conjugation, but occupy sp2 hybrid orbitals, can accept protons, and form salts with strong acids. Imidazole is slightly more basic than pyrazole and pyridine. There is tautomerism in imidazole ring.

  Hydrogen at the 1-site nitrogen atom can be transferred to the 3-site nitrogen atom, so imidazole derivatives with the same substituents at the 4-site and the 5-site, respectively, are tautomers. Imidazole is stable to acid and has antioxidant properties. Imidazole derivatives exist widely in nature. Such as histamine, histidine, benzimidazole and so on.

  
  

  Use: 

  Determination of cobalt. Organic synthesis. Used for anti-metabolism, anti-histamine. Pharmaceutical pesticide intermediates, imidazole is an intermediate of the pesticide apromazole, imidazole and other fungicides, and is also an intermediate of the pharmaceutical antifungal drugs diclobenzimidazole, econazole, ketoconazole and clotrimazole. Used as curing agent for epoxy resin; Used as raw materials for imidazole derivatives, such as gambol, carbonyl diimidazole, etc. Effective buffer in the pH6.2-7.8 range; Used for titration of aspartate and glutamic acid.
