Beschreibung

Anwendung

Reagent for detection of reducing carbohydrates by ESI/MALDI -MS.

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).
