Allgemeine Beschreibung

DL-Mandelic acid is an aromatic hydrocarbon metabolite of styrene.

Anwendung

DL-Mandelic acid may be used as an analytical reference standard for the determination of DL-mandelic acid in:
  • Human urine samples by high performance liquid chromatography (HPLC) equipped with ultraviolet (UV) detector.
  • Rat urine samples by gas chromatography-mass spectrometry (GC-MS) with selected ion monitoring (SIM) detection.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
