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.

The crystal structures of four polymorphs of the pesticide dithianon (5,10-dihydro-5,10-dioxonaphtho[2,3-b]-1,4-dithiine-2,3-dicarbonitrile) have been solved from powder diffraction data and refined using the Rietveld method. Three polymorphs crystallize in non-centrosymmetric space groups. Two polymorphs have Z' > 1. The structures are
