General description
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This 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.

Chlorimuron-ethyl is a member of sulfonylurea herbicides used wildly for pre- and post-emergence control of broad-leaved weeds in soybeans, maize, peanuts, beans, and other crops. It is characterized by very low application rates, high herbicidal activity, good crop selectivity, and low toxicity.
Chlorimuron-ethyl is an acetolactate synthase (ALS) inhibitor, that acts by inhibiting the biosynthesis of the essential amino acids like valine, leucine, and isoleucine. This stops the plant growth as cell division of growing roots and shoots tips are inhibited.

Application
The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques. Chlorimuron-ethyl CRM may also find following uses:
- To develop and validate an RP-HPLC method for the determination of metsulfuron-methyl, chlorantraniliprole, and chlorimuron-ethyl residues in stems of Oryza sativa
- To study the rate of biodegradation of chlorimuron-ethyl using Pseudomonas sp. LW3 in liquid culture and contaminated soil
- To investigate the toxicological effects of chlorimuron-ethyl, cadmium, and copper on germination rate and shoot and root elongation of wheat Triticum aestivum
- Study the effect of chlorimuron-ethyl on physiological mechanisms in wheat and identify valuable biochemical biomarkers for the pollution of chlorimuron-ethyl in soil-plant systems
- Study the biochemical responses to joint stress of chlorimuron-ethyl and cadmium in wheat Triticum aestivum
- To study the photolysis of chlorimuron-ethyl on a soil surface, under sunlight and UV light
- To determine the photodegradation kinetics of chlorimuron-ethyl in an aqueous solution under sunlight and UV light

Investigation of the toxicological effects of some agricultural pollutants on germination rate and on shoot and root elongation of wheat (Triticum aestivum) was carried out. Seeds of wheat were exposed to various concentrations of chlorimuron-ethyl with or without cadmium and

Changes in the activity of antioxidant enzymes including peroxidases (POD) and superoxide dismutases (SOD) and in the contents of chlorophyll (CHL), malondialdehyde (MDA), and soluble proteins (SP) in wheat (Triticum aestivum) under the stress of chlorimuron-ethyl in soil were examined.

The chlorimuron-ethyl-degrading bacterium LW3 was isolated from contaminated soil and identified by 16S rRNA gene sequencing as Pseudomonas sp. When chlorimuron-ethyl was provided as the sole nitrogen source, the degradation efficiency in liquid medium was about 81.0% after 7 days

In this study, the effects of cultivation conditions on the degradation of chlorimuron-ethyl by Stenotrophomonas maltophilia D310-3, which exhibits a high chlorimuron-ethyl-degrading capability, were investigated. To improve the biodegradation efficiency, the cultivation conditions were optimized using response surface methodology (RSM)

Biochemical responses to joint stress of chlorimuron-ethyl and cadmium (Cd) in wheat Triticum aestivum were examined. The joint action of chlorimuron-ethyl and Cd weakened the inhibition of Cd or chlorimuron-ethyl on the formation of chlorophyll. It was deduced that wheat
