Description

General description

Thionazin is a pre- and post-emergence,[1] organophosphorus pesticide (OPP), extensively used in agriculture to combat agricultural pests.[2]

Application

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

Thionazin may be used as an analytical reference standard for the determination of the analyte in :

• Soil and marine sediment samples using supercritical fluid extraction with dispersive liquid–liquid microextraction followed by gas chromatography-flame ionization detection (GC-FID).[2]
• Human blood samples using liquid-liquid extraction followed by gas chromatography and liquid chromatography coupled to electrospray ionization-tandem mass spectrometry in multiple reaction monitoring (MRM) mode.[3]
