Determination of uranium by cupferron with complexone iii as the masking agent

Analytica Chimica Acta, 1956
Abstract The reagent cupferron has been found to be effective for the separation of titanium from Zr+4, Th+4 ,Fe+3, Al+3, Cr+3, rare earths, Pb+2, Cu+2, Cd+2, Bi+3, Sb+3, Zn+2, Mn+2, Ni+2, Co+2 Ca+2, Ba+2, Sr+2, alkalis, AsO3-3, AsO4-3, VO4-3, MoO4-2, WO4-2 and B4O7-2 in the prese complexone III at a pH between 4.3 and 7.0.

Über chlorsubstituierte Derivate des Cupferrons

Chemische Berichte, 1958
AbstractDie relative Chelatstabilität von Cupferron und einiger seiner chlorierten Derivate wurde durch Aciditäts‐und polarographische Messungen bestimmt. Innerhalb der Untergruppe der Monochlor‐oder Dichlor‐Derivate besteht ein direkter Zusammenhang zwischen Chelatstabilität und fungitoxischer Wirkung, jedoch ist eine allgemeine Korrelation nicht ...

Cation-exchange of metal ions in organic solvent-cupferron media

Talanta, 1972
Distribution coefficients of 20 metal ions were determined on the strongly acidic cation-exchanger Dowex 50 in a 30:7:1 mixture of chloroform-methanol-lM hydrochloric acid which was 0.1M in cupferron. In this system the distribution coefficients of Fe(in), Ti(TV), Cu(II), Ce(III) and Th are lower by several orders of magnitude than those of Ni, Mn(II),

Intermediate analogue inhibitors of mandelate racemase: N-Hydroxyformanilide and cupferron

Bioorganic & Medicinal Chemistry Letters, 2007
Mandelate racemase (MR) catalyzes the 1,1-proton transfer that interconverts the enantiomers of mandelate. The transition state/intermediate analogues N-hydroxyformanilide (K(i)=2.79+/-0.19 microM) and cupferron (K(i)=2.67+/-0.09 microM) are identified as potent competitive inhibitors of MR.

The Reaction of Nitroxyl (HNO) with Nitrosobenzene Gives Cupferron (N-Nitrosophenylhydroxylamine)

Nitric Oxide, 1998
Nitroxyl (HNO), a penultimate product in the NOS-catalyzed conversion of L-arginine to L-citrulline, generated from Angeli's salt (AS) was determined by trapping it with nitrosobenzene (NB) to produce cupferron. The cupferron thus produced was characterized by complexation with Fe3+, Al3+, Cu2+, or Sn2+.
