Prothiofos is a non-systemic insecticide and belongs to the group of organophosphates. It is an acetylcholinesterase (AChE) inhibitor causing hyperexcitation and impedes the functioning of the nervous system. Prothiofos gets activated by contact and ingestion and is used to control caterpillars, Pseudococcus spp., thrips, cockchafer larvae, cutworms, etc. in vegetables, fruit, maize, sugar cane, sugar beets, tea, tobacco, and ornamentals.
According to the Commission Implementing Regulation (EU) No 2076/2002 of 20th November 2002, prothiofos is not approved for use in the European Union (EU) as a plant protection agent, following Regulation (EC) No. 1107/2009. But a default maximum residue limit of 0.01 mg/kg is applicable for the presence of prothiofos in products of plant and animal origin, according to Art 18(1)(b) Reg 396/2005.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
Prothiofos CRM may also be used as given below:

  • Multi-residue analysis of 160 multiclass pesticides using ethyl acetate (EtAC)/n. hexane mixture for extraction from chamomile, thyme, and marjoram samples and their analysis by gas chromatography-tandem mass spectrometry (GC-MS/MS)
  • Evaluation of an automated QuEChERS procedure for the determination of 270 pesticides residues in celery, eggplant, tomato, leek, green tea, corn, grape, and soybean oil samples using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS)
  • Gas chromatographic-mass spectrometric (GC/MS) analysis of six organophosphorus (OPPs) pesticides in bell pepper samples after a QuEChERS-citrate method based sample extraction
  • Simultaneous determination of 300 pesticide residues in human hair samples by LC- and GC-MS/MS
  • Quantification of 255 pesticide residues in vegetable oil samples using modified QuEChERS with GC-MS/MS based method
  • Method development to determine 133 pesticide residues in Chenpi samples using a modified QuEChERS method based on ―NH2 sorbent and gas chromatography-tandem mass spectrometry (GC-MS/MS)
