Description

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.
