Description General description Dithianons belong to the quinone class of fungicides. Application Dithianon may be used as an analytical reference standard for the determination of dithianon in: • Surface water samples by solid-phase extraction (SPE) and liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (LC-Q-TOFMS). • Honeybees by dispersive-SPE followed by liquid and gas chromatography coupled to tandem mass spectrometry (LC-MS/MS and GC-MS/MS) equipped with electrospray ionization (ESI) and multiple reaction monitoring (MRM) detection. • Apples by quick, easy, cheap, effective, rugged and safe (QuEChERS) extraction as well as high performance thin-layer chromatography (HPTLC) clean-up procedures and GC-MS/MS. • Tomatoes by QuEChERS extraction and LC coupled to triple quadrupole (QqQ) ESI-MS/MS with MRM detection.
