Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1569-17-1, is researched, SMILESS is CC1=C2C=CC=NC2=NC=C1, Molecular C9H8N2Journal, Journal of Heterocyclic Chemistry called Naphthyridine chemistry. VIII. Mass spectra of the 1,x-naphthyridines and some of their methyl derivatives, Author is Paudler, William W.; Kress, Thomas J., the main research direction is NAPHTHYRIDINES; MASS SPECTRA NAPHTHYRIDINES; QUINOLINE.Product Details of 1569-17-1.
The mass spectra of the four parent 1,x-naphthyridines, the 2-, 3-, and 4-monomethyl-1,5-, 1,6-, and 1,8-naphthyridines, seven dimethyl-1,8-naphthyridines, and one trimethyl-1,8-naphthyridine are reported. Evidence for an azatropylium ion intermediate in the fragmentation of the methyl compounds is presented. The fragmentation modes of the naphthyridines are similar to those for the quinolines in addition to several new processes.
