Understanding the chemical properties and precise applications of an active ingredient is fundamental for any professional in the agricultural or chemical industry. Mesotrione, with its CAS number 104206-82-8, is a prime example of a highly effective agrochemical intermediate, valued for its potent herbicidal activity. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier, offers insight into this compound and its critical role in modern agriculture.

Chemically, Mesotrione is classified as a triketone and acts as a selective herbicide. Its IUPAC name, 2-[4-(Methylsulfonyl)-2-nitrobenzoyl]-1,3-cyclohexanedione, details its complex structure. Key properties include a molecular formula of C14H13NO7S and a molecular weight of 339.32 g/mol. It typically presents as a pale yellow crystalline solid with a melting point of 165-166°C, indicating its stable nature under normal storage conditions. Its low vapor pressure (<1×10-5 mPa at 25°C) suggests minimal volatility, which is advantageous for application and environmental handling. Furthermore, its solubility in water (1600 mg/L at 20°C) and solubility in DMSO facilitate its formulation into effective sprayable products.

The primary agricultural application of Mesotrione is as a highly effective herbicide for weed control, particularly in corn crops. Its mechanism of action involves inhibiting the HPPD enzyme, crucial for carotenoid biosynthesis in weeds. This leads to the characteristic bleaching of foliage, growth cessation, and eventual death of susceptible broadleaf weeds and grasses. This makes it an indispensable tool for both pre-emergent and post-emergent weed control, providing flexibility to farmers. Its high selectivity for corn ensures that the crop is protected while weeds are managed efficiently, contributing to optimal yield potential.

Beyond its direct application, Mesotrione is also valued for its role in integrated weed management programs. It offers residual activity against certain weed species and can be used in tank mixes with other herbicides, broadening the spectrum of control and aiding in resistance management strategies. The product's rainfastness within one hour of application further enhances its practical utility, ensuring effectiveness even with unexpected weather events.
