Beschreibung

Allgemeine Beschreibung

Methanolis a high-purity solvent specifically designed for chromatographicapplications. It is used as a mobile phase component in high-performance liquidchromatography (HPLC), gas chromatography (GC), and thin-layer chromatography(TLC).

Anwendung

Methanolcan be used as a derivatization solvent to form the methylated derivatives oftopiramate that can be analyzed using gas chromatography-mass spectrometry(GC-MS) for qualitative and quantitative determination of topiramate in serumsamples.
