Popis

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
