Frymark, Justyna; Zabiszak, Michal; Grajewski, Jakub; Hnatejko, Zbigniew; Kolodynska, Dorota; Kaczmarek, Malgorzata T.; Jastrzab, Renata published the artcile< Excess of polyamine as a factor influencing the mode of coordination in the Eu(III)/α-hydroxy acid/spermine system>, Synthetic Route of 112-63-0, the main research area is europium complexation hydroxy acid spermine excess polyamine spectroscopy.
The complexes of europium(III) ions in binary and ternary systems with α-hydroxy acids and biogenic amine – spermine were investigated. Studies have been performed in aqueous solution using the potentiometric method with computer anal. of the data. Anal. of the equilibrium constants of the reactions and spectroscopic data have allowed us to determine the type of coordination and effectiveness of the carboxyl groups in the process of complex formation in the systems studied. Furthermore, the results confirmed the occurrence of non-covalent interactions of protonated spermine with coordinated α-hydroxy acid. The effect of biogenic polyamine concentration was clearly confirmed, and their influence on the stability and coordination mode of ternary complexes was found.
Polyhedron published new progress about Circular dichroism. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Synthetic Route of 112-63-0.
