In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Spectral data of substituted naphthyridines. V. The IR spectra of substituted 1,8-naphthyridines, published in 1979, which mentions a compound: 1569-17-1, mainly applied to IR naphthyridine derivative, Category: naphthyridine.
In general the IR spectra of 1,8-naphthyridines show a ring bending (skeletal) vibration at 690-740-cm-1, three adjacent H absorption at 750-795 and 810-885 cm-1, two adjacent H absorptions at 785-855 cm-1 and isolated H absorptions at 795-810 and 885-920 cm-1.
From this literature《Spectral data of substituted naphthyridines. V. The IR spectra of substituted 1,8-naphthyridines》,we know some information about this compound(1569-17-1)Category: naphthyridine, but this is not all information, there are many literatures related to this compound(1569-17-1).
