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 Solvent effect on the intramolecular hydrogen bond in 8-quinolinol N-oxide, published in 1996-02-29, which mentions a compound: 1127-45-3, mainly applied to solvent effect hydrogen bond quinolinol oxide; intramol hydrogen bond quinolinol oxide, Recommanded Product: 8-Hydroxyquinoline 1-oxide.
Solvent effect on intramol. hydrogen bond in 8-quinolinol N-oxide has been studied by IR, UV, 1H NMR and 13C NMR spectroscopy, dipole moment measurements and quantum-mech. calculations The solute-solvent interactions are of local character and they vary considerably over the range of solvent under study. The results suggest that formation complexes with solvent mols. weaken the intramol. hydrogen bond in 8-quinolinol N-oxide.
There are many compounds similar to this compound(1127-45-3)Recommanded Product: 8-Hydroxyquinoline 1-oxide. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
