Nicotelline
Nicotelline
Chemical compound
Nicotelline is an alkaloid first identified in 1914 as a chemical constituent of tobacco plants (Nicotiana).[2]
The chemical structure of nicotelline wasn't elucidated until 1956, when it was determined that nicotelline is a terpyridine consisting of three linked pyridine rings.[3] This structure was confirmed by laboratory synthesis.[3][4] Nicotelline has the molecular formula C15H11N3. It is a crystalline solid with a melting point of 147-148 °C.[1] It is soluble in hot water, chloroform, ethanol, and benzene.[1]
Nicotelline has long been known to be a constituent of tobacco smoke.[5] As such, it has recently been proposed as a biomarker or environmental tracer for tobacco smoke.[6]
