一般描述
Metazachlor is an α-chloracetamide derivative which is widely used as a herbicide for weed control in the cultivation of crucifers such as rape.
应用
Metazachlor may be used as an analytical standard for the determination of metazachlor in:
- Natural water samples by high performance liquid chromatography-electrospray-tandem mass spectrometry (HPLC-ESI-MS/MS).
- Plant foodstuffs by capillary gas chromatography equipped with electron capture detector (ECD) as well as nitrogen phosphorus detector (NPD) followed by MS analysis in electron impact ionization (EI) mode.
- Drinking and related waters by solid phase extraction (SPE) followed by GC-EI-MS.
- Wastewater samples by SPE and subsequent analysis with ultra-performance liquid chromatography combined with time of flight mass spectrometry (UPLC-TOF-MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

The present study aimed to develop and prepare new polymer/herbicide formulations for their potential application in environment-friendly, controlled release systems of agrochemicals. Selected biodegradable polymers, including L-Lactide/Glycolide/PEG/Terpolymer (PLAGA-PEG-PLAGA) as well as oligosaccharide-based polymers and their blend with terpolymer, were used
