benzopyridine

Benzopyridines are a class of organic compounds that are heterocyclic, meaning they contain ring structures with atoms of more than one element. Specifically, benzopyridines consist of a benzene ring fused with a pyridine ring.1

There are isomeric forms of benzopyridines, and they, along with dibenzopyridines, can be found in coal tar. These compounds are the parent structures for various alkaloids. Notable examples include quinolines, such as quinine, and isoquinolines, like morphine.1

Benzopyridine derivatives have diverse applications, including the manufacturing of chemicals like nicotinic acid, as well as in the production of drugs and dyes. They are also used in creating cyanine dyes for photographic emulsions and quinophthalone dyes for plastics and textiles.1
