Chemical and Physical Properties
Mesotrione is a light yellow opaque solid with a faint pleasant odour. It dissolves at a rate of 2.2 g/l at 200 C in unbuffered water whose pH is 4.8. It also dissolves in n-heptane <0.5, xylene 1.6, toluene 3.1, methanol 4.6, ethyl acetate 18.6, 1,2-dichloroethane 66.3, acetone 93.3, and in acetonitrile 117.0, all in g/l at 200 degree C.
Mesotrione has a molecular weight of 339.318 g/mol, a monoisotopic mass of 339.041 g/mol and an exact mass of 339.041 g/mol. It has a heavy atom count of 23 and a complexity of 627.
Uses
Mesotrione is a herbicide that works by inhibiting 4-hydroxyphenylpyruvate dioxygenase (HPPD), a crucial enzyme for the biosynthesis of carotenoid in plants. Mesotrione is also a synthetic analog of l epospermone.
Mesotrione is available as a soluble solid or concentrates, as a pressurized liquid, a ready to use solution, soluble concentrate, emulsifiable concentrate, water dispersible granules and in granular form.
Some of its premix partners may include Terbuthylazine, Rimsulfron, Nicosulfron, S-Metolachlor, Glyphosphate and Atrazine.
