Amidine
Definition
An organic compound functionally derived from a carboxamide where the oxo group (=O) has been replaced by an imino group (=NR), having the general structure R-C(=NR)-NR2. Amidines are structurally recognized as strong organic bases due to the resonance stabilization of the cation resulting from protonation, their core being frequently used in the synthesis of antiparasitic, antifungal drugs, and clinical diagnostic agents.
