In the continuous effort to enhance agricultural productivity and sustainability, understanding the chemical intricacies of active ingredients is paramount. Quizalofop-P-Ethyl, identified by its CAS number 100646-51-3, is a vital selective herbicide with a significant impact on weed management strategies. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical manufacturer and supplier, provides this crucial compound and offers insights into its chemical profile and agricultural significance.

The chemical identity of Quizalofop-P-Ethyl is ethyl (R)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propionate, with the molecular formula C19H17ClN2O4. Its molecular weight is approximately 372.8 g/mol. The compound is characterized by its specific R-enantiomeric configuration, which is key to its herbicidal activity. It typically presents as a light yellow liquid or solid, with a purity standard of 98.0% minimum, ensuring its effectiveness as a post-emergence herbicide. The primary mechanism of action involves the inhibition of acetyl-CoA carboxylase (ACCase) in susceptible grass weeds. This enzyme is essential for the synthesis of fatty acids, which are building blocks for cell membranes. By disrupting this process, Quizalofop-P-Ethyl leads to the breakdown of cell membranes and the eventual death of the weed. This targeted action makes it particularly valuable for selective application in broad-leaved crops such as soybeans, cotton, peanuts, and potatoes, where it effectively eliminates grassy weeds without harming the crop itself.

The agricultural impact of Quizalofop-P-Ethyl is substantial. By providing effective control over annual and perennial grassy weeds, it helps to prevent yield losses that can be as high as 30-50% in severe infestations. This leads to increased farm profitability and more secure food supplies. For agrochemical companies and distributors, the consistent availability of high-quality Quizalofop-P-Ethyl is critical. NINGBO INNO PHARMCHEM CO.,LTD. is committed to being a reliable supplier, offering competitive pricing and consistent product quality.
