In this work, the formation of ternary complexes with their resp. formation constants in the systems formed by copper (II), picolinic acid and the amino acids = histidine (His), aspartic acid (HGly), proline (HPro), α-alanine (HαAla), β-alanine (HβAla), serine (HSer), threonine (HThr), phenylalanine (HPhe) and methionine (HMet) was detected. The anal. involves the use of the potentiometric data with the least-squares program LETAGROP in aqueous solution at 25°C in 1M KNO3 solution The relative stability of the ternary complexes was compared with the binary ones considering the values of Δlog K and log χ. Subsequently using the formation constants, the species distribution diagrams were generated and are briefly discussed here. The Cu (II)-picolinic acid-glutamic acid, Cu (II)-picolinic acid-serine and Cu (II)-picolinic acid-histidine systems were characterised by UV-Vis mol. absorption spectroscopy and cyclic voltammetry, obtaining results that confirm the formation of ternary complexes with octahedral geometry. In the part of experimental materials, we found many familiar compounds, such as Picolinic acid(cas: 98-98-6Computed Properties of C6H5NO2)
Picolinic acid(cas: 98-98-6) is used in the preparation of 2-Aminodihydro[1,3]thiazines as BACE 2 inhibitors and their preparation and use in the treatment of diabetes.Computed Properties of C6H5NO2
