CHLORBROMURON Chemical Properties,Usage,Production

Uses

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

Definition

ChEBI: Chlorbromuron is a member of ureas.

Metabolic pathway

The main photoproducts initially formed in the phototransformation of linuron and chlorbromuron in aqueous solution result from photolysis, i.e. hydroxylation with release of the halide ion, and from elimination of a methoxy group. The orientation of the reaction depends on the wavelength: short wavelengths (254 nm) favor demethoxylation and photolysis in the meta position,whereas, with black light longer than 330 nm, photolysis in the para position is the main reaction observed. In soils, 4-bromo-3-chloroaniline is identified as a soil degradation product of chlorbromuron.
