Chiral High-performance Liquid Chromatographic Method for Enantioselective Analysis of Zaltoprofen

A simple reversed-phase chiral HPLC method has been developed and validated for direct separation of the enantiomers of zaltoprofen. Separation of the enantiomers was tested on numerous commercial chiral HPLC columns. Separation was best (resolution, RS = 3) on a Chiralcel OJ-RH stationary phase. Typical retention times of the S and R enantiomers were approximately 14 and 16 min, respectively. ...

Review High-performance liquid chromatographic enantioseparation of drugs containing multiple chiral centers on chiral stationary phases

In recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. High-performance liquid Chromatography is a very useful method for the direct separation of enantiomers. However, about 30−40 years ago, commercially available chiral stationary phases wer...

High Pt Loading on Polydopamine Functionalized Graphene as a High Performance Cathode Electrocatalyst for Proton Exchange Membrane Fuel Cells

Morphology and size of platinum nanoparticles are a crucial factor in improving their catalytic activity and stability. Here, we firstly report the synthesis of high loading Pt nanoparticles on polydopamine reduced Graphene. The loading concentration of Pt (nanoparticles) NPs on Graphene can be adjusted in the range of 60-70%.With the insertion of polydopamine between Graphene oxide sheets, sta...

Chiral Pt/ZrO2 catalysts. Enantioselective hydrogenation of 1-phenyl-1,2-propanedione.

The enantioselective hydrogenation of 1-phenyl-1,2-propanedione over Pt colloids stabilized with (R,S)-4,5-dihydro-4,5-diphenyl-2-(6-cyanopyridinyl)imidazoline (CI) supported on a meso-structured ZrO(2) under a pressure of 40 bar of H(2) at 298 K has been investigated(.) The metal loading in all catalysts was 1 wt%. The effect of the amount of chiral modifier on the metal particle size and on t...
