Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate. Download your certificate at: http://www.sigma-aldrich.com

Ethirimol is the ethylamino isomer of dimethirimol that belongs to a group of pyrimidine fungicides. This systemic fungicide acts by inhibiting nucleic acid synthesis and is used as a seed treatment to control powdery mildew in spring barley and wheat. Ethirimol is not approved for use in European Union (EU) as per Regulation (EC) No 1107/2009. But a default maximum residue level (MRLs) from 0.01 mg/kg to 2 mg/kg is applied for products of plant and animal origin, according to Regulation (EU) 2021/1531.

Ethirimol has to be monitored in the Multiannual Control Programme for Pesticides Residues (MACP), run within the EU and EFTA in/on products of plant origin.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
The Ethirimol CRM may also find following uses:

• Simultaneous determination of the captan, captafol, carbendazim, chlorothalonil, ethirimol, folpet, metalaxyl, and vinclozolin from drinking, river, and estuarine water using solid-phase disk extraction followed by gas and liquid chromatography
• Study the effects of commercial nonionic polyoxyethylene surfactants on the foliar penetration and movement of ethirimol and diclobutrazol from suspension formulations applied to wheat plants at different growth stages
• Study the key ultrastructural responses of Erysiphe graminis in barley due to the effects of ethirimol and propiconazole fungicides
• Development of QuEChERS-ultra performance liquid chromatography-tandem mass spectrometry analysis method for residual determination of thiophanate-methyl, carbendazim, and ethirimol in strawberry
• Study the effect of pressurized fluid extraction (PFE) on the recovery of bupirimate and its degradation product, ethirimol from a range of soil types
