2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.COA of Formula: C8H11N

Natural and transmission line produced positive ions was written by Eisele, F. L.. And the article was included in Journal of Geophysical Research, [Atmospheres] in 1989.COA of Formula: C8H11N This article mentions the following:

Pos. ions were studied at 3 field sites, 2 of which contained ions produced by high-voltage d.c. (HVDC) transmission lines. Natural ions were studied at 2 of the 3 sites. The observed differences between natural and anthropogenic ion spectra near HVDC lines are attributed primarily to a shortening of ion lifetimes by the strong elec. field associated with the HVDC lines. One exception is the production of K and probably Na based ions from the decomposition of insects in transmission line coronas. Several ions which have been observed previously at mass 60 and 130 were identified for the first time, using tandem mass spectrometric techniques, as trimethylamine and quinoline (and isoquinoline), resp. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4COA of Formula: C8H11N).
