    • Electrochemical reduction of diazepam

      L Thomas J L Vilchez G Crovetto J Thomas

      More Details Abstract Fulltext PDF

      The reduction of 7-chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepine-2-one at the dropping mercury electrode has been investigated. The process is diffusion controlled; furthermore, the reduction wave enables the quantitative determination of the drug both in acid and basic media. The reagent captures two electrons and two hydrogen ions. A disproportionation reaction of the hydrazo-compound takes place, and amines are the final reduction products.

    • Nanostructured phosphomolybdates

      More Details Abstract Fulltext PDF

      Phosphomolybdate nanorods were synthesized using dodecyl pyridinium cations as structure directing agent. Composition and morphology of the nanorods were established by powder X-ray diffraction, energy dispersive X-ray analysis, fourier transform infrared spectroscopy, thermogravimetric analysis, transmission electron microscopy and scanning electron microscopy. Effect of synthetic variables such as pH and nature of templating agent on structure and morphology of the nanorods under ambient condition is discussed.
