Chlorbromouron is an obsolete systemic phenylurea herbicide used for pre- and post- emergence control of annual grasses (e.g. foxtail) and broad leafed weeds (e.g. chickweed) on a variety of crops. It inhibits photosynthesis by interfering with the electron transfer in photosystem II. As per the commission regulation no 1107/2009, repealing the council directive 91/414/EEC, chlorobromouron is not approved for use in the European Union. A default maximum residue limit (MRL) of 0.01 mg/kg is set for chlorbromuron as per regulation (EC) no. 396/2005.

Zastosowanie

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

• Method development for the quantification of 25 polar pesticides in fruit, vegetable, and water samples using high-performance liquid chromatography(HPLC)
• Separation and determination of 12 substituted phenylurea herbicides by HPLC in the study to assess the leaching of the herbicides in two agricultural soil samples
• Development of an HPLC method with diode array detection following dispersive liquid-liquid microextraction to determine 11 phenylurea herbicides in natural waters
• Investigation of 1,6-hexanediol ethoxylate diacrylate (HEDA)-based polymeric monoliths as a sorbent for the extraction of phenylurea herbicides from water samples
• Multi-residue analysis of 250 pesticides in surface water samples using liquid chromatography- quadrupole-Orbitrap high resolution tandem mass spectrometry
