Phosphamidon is a broad-spectrum systemic organophosphorus pesticide. It is used as an insecticide against sap-feeding insects, rice-stem borers, and rice leaf beetles in crops of sugarcane, citrus fruits, commercial cotton, and nuts.
As per Regulation (EC) No. 1107/2009, repealing directive 91/414/EEC, phosphamidon is not approved for use in the European Union. But a default maximum residue limit (MRL) of 0.01 mg/kg is applicable for the presence of phosphamidon in products of plant origin, in accordance with Regulation (EC) No. 149/2008.

Application

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

• Determination of five organophosphorus pesticides in a medicinal herb sample using QuEChERS along with dispersive liquid-liquid microextraction (DLLME) and stacking followed by micellar electrokinetic chromatography (MEKC)
• Magnetic solid phase microextraction (MSPE) of five organophosphorus pesticides using graphene based cyanopropyltriethoxysilane as an adsorbent from cow′s milk samples and their subsequent determination by gas chromatography with micro-electron capture detector
• Investigation of residue levels of highly toxic pesticides in 6554 samples of fruits and vegetables by quadrupole time-of-flight LC/MS
• Analysis of 4 organophosphorus pesticides by gas chromatography with microelectron capture detector following their extraction using a newly synthesized magnetic hybrid material as a solid phase extraction adsorbent
• Multi-residue analysis of 44 organophosphorus pesticides by QuEChERS method combined with gas chromatography in Pogostemon cablin samples
• Detection of organophosphorus pesticides in Chinese cabbage sample by a newly designed positive photoionization-ion mobility spectrometry (PP-IMS) apparatus
