    Description / Table of Contents: Zusammenfassung 1-Carbamido-, 1-Thiocarbamido- und 1-Carbamidino-3-methyl-pyrazolon-5 wurden durch Reaktion von Äthylacetoacetat mit Semicarbazid, Thiosemicarbazid. und Aminoguanidin dargestellt und auf ihre Verwendbarkeit zur Bestimmung von Metallionen untersucht. CuII und PdII können gravimetrisch und FeIII, UVI sowie OsVI colorimetrisch mit gutem Erfolg bestimmt werden.
    Notes: Summary 1-carbamido-. 1-thiocarbamido- and 1-carbamidino-3-methyl-pyrazolone-5 have been prepared by the reaction of ethyl acetoacetate with semicarbazide, thiosemicarbazide and aminoguanidine respectively. The reactions of these pyrazolone derivatives with metallic ions have been studied with a view to study their analytical application and it has been found that they can be satisfactorily employed for the gravimetric estimations of CuII and PdII, as well as for the colorimetric estimations of FeIII, UVI and OsVI.
