Metabolite Identification
Common NameIsoquinoline
DescriptionIsoquinoline, also known as 3,4-benzopyridine or beta -quinoline, belongs to the class of organic compounds known as isoquinolines and derivatives. These are aromatic polycyclic compounds containing an isoquinoline moiety, which consists of a benzene ring fused to a pyridine ring and forming benzo[c]pyridine. Isoquinoline exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule.
