What is imidazole pka?

Imidazole pKa is the measure of the acidity or basicity of imidazole, which is a heterocyclic organic compound with the formula C3H4N2. It has five carbon atoms and two nitrogen atoms arranged in a ring shape. The pKa value of imidazole is 7.0, which means it is a weak base and a weak acid. This makes it a useful buffer in biochemical and chemical reactions. The nitrogen atoms in imidazole have a lone pair of electrons that can participate in hydrogen bonding, making it an important component of many catalytic enzymes, hormones, and other biomolecules. Imidazole is also used in pharmaceuticals, as an antifungal agent, and in other industrial applications.
