Application

3-Methyl-1-phenyl-2-pyrazoline-5-one may be used:
  • As a reagent for the detection of reducing carbohydrates by ESI/MALDI-MS.
  • To improve the sensitivity of reducing mono- and oligo-saccharides for their subsequent determination using capillary zone electrophoresis.
  • For the precolumn derivatization of the monosaccharide components of Salvia miltiorrhiza, liguspyragine hydrochloride, and glucose injection prior to their analysis by high performance liquid chromatography (HPLC).

Salvia miltiorrhiza, liguspyragine hydrochloride, and glucose injection (SLGI) was made of Salvia miltiorrhiza Bge., liguspyragine hydrochloride, glucose, and glycerin. There were many kinds of monosaccharide components in SLGI, which might be from the raw material and Salvia miltiorrhiza Bge. Separation

We synthesized various 3-methyl-1-phenyl-5-pyrazolone (edaravone) derivatives and evaluated their oxidation potential and hydroxyl radical scavenging activity. It was found 3-methyl-1-(pyridin-2-yl)-5-pyrazolone had a much higher ability to scavenge the radical than did edaravone itself. Its efficient radical scavenging activity was assumed
