Organic base

An organic base is an organic compound which acts as a base. Organic bases are usually, but not always, proton acceptors. They usually contain nitrogen atoms, which can easily be protonated. For example, amines or nitrogen-containing heterocyclic compounds have a lone pair of electrons on the nitrogen atom and can thus act as proton acceptors. Examples include:pyridine alkylamines, such as methylamine imidazole benzimidazole histidine guanidine phosphazene bases hydroxides of quaternary ammonium cations or some other organic cations
