Diclofop-methyl is a post-emergence chiral herbicide that belongs to the class of aryloxyphenoxy propanoate (AOPP) compounds. It prevents the synthesis of fatty acids by inhibiting the activity of acetyl CoA carboxylase (ACCase). Diclofop-methyl is a selective and systemic herbicide used against wild oats, wild millets, and other annual grass weeds in broad-leaf crops, wheat, barley, maize, sorghum, oats, sugar cane, rice, dicotyledonous vegetables, and cotton. It causes an immediate inhibitory effect on the growth of the shoot, intercalary, and root meristems of the plant. It quickly hydrolyzes to give diclofop in plants, water, and soil.
Diclofop-methyl was included on 1st June 2011 in Annex I of Directive 91/414/EEC by the European Commission Directive 2011/45/EU. Diclofop-methyl is approved for use in the European Union under EC Regulation No 1107/2009, as per the Commission Implementing Regulation (EU) No 540/2011, however it is a candidate for substitution.

Application
The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
The diclofop-methyl CRM may find its use as described below:
The diclofop-methyl CRM may find its use as described below:
- To study the enantioselective degradation of diclofop-methyl and diclofop in two soil samples under aerobic and anaerobic conditions using high-performance liquid chromatography (HPLC)
- Simultaneous extraction and determination of enantiomers of diclofop-methyl and diclofop in cole using high-performance liquid chromatography-chiral stationary phase (HPLC-CS)
- Development of a multi-residue method for simultaneous estimation of 16 pesticides in water samples using direct immersion SPME followed by GC-MS analysis
- Simultaneous extraction and determination of aryloxyphenoxy-propionate herbicides from water samples by dispersive magnetic solid-phase extraction (d-MSPE) with high-performance liquid chromatography-diode array detector (HPLC-DAD) and ultra-high pressure liquid chromatography -triple quadrupole mass spectrometer (UHPLC-MS/MS)
- Evaluating the capacity of silica-bonded deoxycholic acid as a stationary phase having a 3,5-dinitrophenylcarbamoyl and a calix[4]arene substituent for enantiomeric separations
