A simple, selective and sensitive derivative spectrophotometric method has been developed for the determination of palladium(II) using a newly synthesised reagent diacetylmonoxime-(p-anisyl)-thiosemicarbazone in acetic acid medium. The molar absorptivity and Sandell’s sensitivity of the coloured species are 3.8 × 10 L mol cm and 2.8 ng cm, respectively. Beer’s law is obeyed between 0.2-2.0 μg m...

A simple, selective and sensitive spectrophotometric method has been developed for the determination of tin(II) using a newly synthesised reagent diacetylmonoxime p-hydroxybenzoylhydrazone in cationic micellar medium. The molar absorptivity and Sandell’s sensitivity of the coloured species are 3.20×10 L mol cm and 3.6 ng cm respectively. Beer’s law is obeyed between 0.25-2.76 μg mL of Sn(II)) a...

The present study aimed to synthesize new metal complexes of diacetylmonoxime-N(4)antipyrinylthiosemicarbazone ligand and evaluate their antitumor activity. New with ferric, cobalt, nickel copper ions were prepared. Elemental, 1H Nuclear magnetic resonance, Mass spectroscopy, Electron paramagnetic Fourier Transform Infrared Spectroscopy, Ultraviolet–visible thermal gravimetric analysis used cha...

nickel(ii) complex of [nil2](clo4)2, where l is an unsymmetrical tridentate ligand of 2-(2-aminoethyl)imino-3-butanone oximehas been synthesized by a template condensation reaction. the complex was characterized on the basis of microanalytical, spectroscopic, and other physicochemical properties. x-ray diffraction study of the complex reveals nickel(ii) center in a distorted octahedral environm...

ErOIN, or diacetyl morphia, is chiefly used in this country as Sedati^e in cases of troublesome cough, and is generally given ^ the hydrochloride in a mixture. I am informed, however, by essrs. Burroughs and Wellcome, that it is largely used at the Plesent time hypodermically, chiefly, I imagine, for the relief of Pain or the control of asthma. It is desirable, therefore, that rriedical men sho...

A rapid and reproducible method is described for measurement of urea in biological materials (after deproteinisation) and in serum (without deproteinisation). Urea is colorimetrically determined with diacetyl monoxime and thiosemicarbazide in the presence of sulphuric acid, phosphoric acid and ferric chloride. The sensitivity of the colorimetric reaction and stability of the colour are enhanced...

Unlike other excitation-contraction uncouplers, blebbistatin has few electrophysiological side effects and has gained increasing acceptance as an excitation-contraction uncoupler in optical mapping experiments. However, the possible role of blebbistatin in ventricular arrhythmia has hitherto been unknown. Furthermore, experiments with blebbistatin and 2,3-butanedione monoxime (BDM) offer an opp...

Automated and manual direct methods for the determination of urea in blood or serum are described. These methods determine urea by the colored product formed when urea, in relatively weak acid solution, reacts with diacetyl monoxime in the presence of thiosemicarbazide and ferric ion. Results are compared with those obtained by urease conversion of urea to ammonia and measurement of the ammonia...
