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]
