Osmometric studies on self-association of pyrimidines in aqueous solutions: evidence for involvement of hydrophobic interactions was written by Plesiewicz, Ewa;Stepien, Elzbieta;Bolewska, Krystyna;Wierzchowski, K. L.. And the article was included in Biophysical Chemistry in 1976.HPLC of Formula: 39513-47-8 The following contents are mentioned in the article:
Vapor pressure osmometric studies were performed on stacking self-association of 25 uracil derivatives variously C- and N-substituted with polar and alkyl groups in aqueous solution at various temperatures The respective equilibrium association constants KSt were computed on the assumption of the isodesmic model of self-association Enthalpies of association for most of the compounds studied were obtained from the temperature-dependence of KSt, according to the van’t Hoff equation. Anal. of the equilibrium and thermodn. parameters in terms of the association mechanism demonstrated the involvement of classical hydrophobic interactions in the stabilization of complexes of di- and higher alkylated uracils. Data for the derivatives substituted with polar groups proved consistent with the predominant involvement of dipole-induced dipole forces in the association This study involved multiple reactions and reactants, such as Ethyl 1,3-dimethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (cas: 39513-47-8HPLC of Formula: 39513-47-8).
Ethyl 1,3-dimethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (cas: 39513-47-8) belongs to pyrimidine derivatives. Pyrimidine also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. We all know its importance to life – pyrimidine and purine bases are included in the structure of DNA and RNA.HPLC of Formula: 39513-47-8
