General description
Imidazole is a five-membered heterocycle that is found in many naturally occurring compounds. It exhibits both acidic and basic properties. It is reported to be an inhibitor of thromboxane formation. Its vertical spectrum and the radiationless decay have been recorded and analyzed.
Application
Excellent for buffers in the range of pH 6.2-7.8

A great number of structurally diverse natural products containing five-membered heterocyclic subunits, such as imidazole, oxazole, thiazole, and their saturated congeners, are abundant in nature. These naturally occurring metabolites often exhibit extensive and pharmacologically important biological activities. The latest progress
