Pharmaceutical raw materials Imidazole with CAS 288-32-4
Imidazole is a five-membered aromatic heterocyclic compound with two intermediate nitrogen atoms in the molecular structure. Unshared electron pairs of 1-position nitrogen atoms in the imidazole ring participate in the cyclic conjugation. The electron density of nitrogen atoms decreases, which makes the hydrogen on this nitrogen atom easily depart in the form of hydrogen ions. Therefore, imidazole has weak acidity and can form salt with strong base. The 3-position nitrogen atoms in the imidazole ring, which occupy the SP2 hybrid orbital and do not participate in conjugation, can accept protons and form salts with strong acids. The alkalinity of imidazole is slightly stronger than that of pyrazole and pyridine.
