General description
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. The CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.

Fenoxaprop-P-ethyl (FPE) is a post-emergence herbicide that is used on many crops, such as rice, wheat, and barley, against annual and perennial grasses. It is an aryloxyphenoxypropionate that shows contact and systemic action. Fenoxaprop-P-ethyl works by inhibiting the activity of acetyl coenzyme A carboxylase and disrupting the synthesis of fatty acids. It is quickly converted to its metabolite fenoxaprop acid (FPA), another herbicidally active compound, in soil and plants. As per the commission regulation no 1107/2009, repealing the council directive 91/414/EEC unless otherwise stated the data available for fenoxaprop-P relates to its variant fenoxaprop-P-ethyl. It was approved for use in European Union on 1st January 2009 and the approval expires on 31st December 2022. According to Regulation (EC) no. 149/2008, a maximum residue limit (MRL) of 0.1 mg/kg applies for fenoxaprop-P in fresh/frozen fruits and tree nuts.

Application
The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
The CRM may also find the following uses:
The CRM may also find the following uses:
- Development and validation of gas chromatography (GC) and high-performance liquid chromatography (HPLC) method to detect FPE and its two primary metabolites in rice plants, rice straw, and rice grain
- Study of the degradation of FPE and its metabolite in soil and wheat crops by high-performance liquid chromatography (HPLC) coupled with UV detector
- Determination of FPE in barley and wheat grain samples using UV-Vis spectrophotometer
- Residue analysis of FPE and its metabolite fenoxaprop acid using HPLC in the study to evaluate the persistence of the herbicide and its metabolite in soil, wheat grain, and straw
- Development of a multi-residue enzyme-linked immunosorbent assay (ELISA) to detect two aryloxyphenoxypropionate herbicides in water, rice, soil, and soybean samples
- Direct determination of FPE from water and crop samples by voltametric method and also analysis of its reduction behavior on a hanging mercury drop electrode (HMDE)

The dissipation kinetics of fenoxaprop-p-ethyl and its metabolite (fenoxaprop acid) at two application rates under wheat field conditions for two seasons was investigated. Herbicides were extracted by solid liquid extraction, cleaned up, and analyzed by a liquid chromatography-UV detector. Dissipation
