Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 3724-19-4, is researched, Molecular C8H9NO2, about Cupric chelates of pyridinic acids. I. Monoacids, the main research direction is pyridine acid copper complex; copper pyridine acid.HPLC of Formula: 3724-19-4.
The pyridine monoacids (x-Q-(CH2)nCO2H), where x is the position of the substituent chain (2, 3 or 4 with respect to the heterocyclic N) and n = 0, 1, or 2, in aqueous solutions formed complexes with Cu2+ at Cu2+/complexing agent ratios of 1:1 and 1:2, except the 2-pyridinepropionic acid which did not give the 1:2 complex. The 2-pyridinemethanoic acid (or picolic acid, 2-QCO2H) was the only one to give, in alk. medium, a hydroxy complex: [Cu(2-QCO2)(OH2)]-. The acidity constants of the complexing agent mols. were measured by potentiometry and uv spectrophotometry. The formation constants of the complexes of the acids in positions 2 and 3 were calculated by potentiometry, polarog., and spectrometry. The stability of the complexes depend much more on the length and on the spatial configuration of the chelated rings than on the acidity of the complexing agent mols.
《Cupric chelates of pyridinic acids. I. Monoacids》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(3-Pyridinepropionic acid)HPLC of Formula: 3724-19-4.
