Monolinuron is a systemic and selective phenylurea herbicide, absorbed mainly through roots and leaves. It binds to the QB site on the D1 protein of the photosystem II complex and inhibits the photosynthetic electron transport. Monolinuron is used for pre- and post-emergence control of annual broad-leaved and some grass weeds in asparagus, berries, maize, dwarf French beans, field beans, vines, leeks, onions, potatoes, herbs, alfalfa, flowers, and ornamental shrubs and trees.
Monolinuron is not approved for use in the European Union (EU) as a plant protection agent, according to Regulation (EC) No. 1107/2009, repealing the Directive 91/414/EEC. But default maximum residue levels of 0.01 mg/kg to 0.05 mg/kg are allowed for its presence in products of plant and animal origin, according to the EU Reg. No 2015/868.

Application

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

• Determination of 252 pesticides extracted from surface water samples by solid-phase extraction (SPE) using liquid chromatography quadrupole-orbitrap high-resolution tandem mass spectrometry
• Extraction of 13 pesticides from four groundwater and three river water samples using silica-based MSU-1 mesoporous solid as a sorbent for their solid-phase extraction (SPE) followed by ultra-performance liquid chromatography-triple quadrupole-mass spectrometric (UHPLC- QqQ-MS/MS) determination
• Development and validation of a UHPLC-diode array detection (DAD) method for simultaneous determination of urea and tebuthiuron herbicides in four fresh vegetable samples
• Multi-residue analysis of 50 herbicides in 51 grain samples of soybean, corn, and wheat by ultra-performance liquid chromatography-electrospray ionization-mass spectrometry (UPLC-ESI-MS)
• Extraction of 109 pesticide residues from different chemical classes from 345 tomato samples by modified QuEChERS method and their determination using liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• Simultaneous analysis of 238 pesticides and 78 veterinary drugs in 80 bovine milk samples using ultra-fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS)
