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 with a pH of 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 acetonitrile (117.0), all in g/L at 200 °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 carotenoid biosynthesis in plants. Mesotrione is also a synthetic analog of lepospermone.
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.
