定義
ChEBI: A member of the class of 1,2,4-triazines that is 1,2,4-triazin-5(4H)-one substituted by an amino group at position 4, a methyl group at position 3 and a phenyl group at position 6.
一般的な説明
4-Amino-3-methyl-6-phenyl-1,2,4-triazin-5-one, commonly known as metamitron, is a pesticide having low polarity and is hydrophobic in nature. Its pKa value is 2.9.
农业用途
Herbicide: Metamitron is a selective systemic herbicide that is absorbed through roots and leaves and inhibits photosynthesis. It is used to control grasses and broadleaf weeds in sugar beets and fodder beets. Not currently registered in the U.S. Used in most European countries and having 34 global suppliers .

代謝経路
Degradation of metamitron by photolysis is strongly dependent on solvents and oxygen, and no photoreaction is found in methanol, acetonitrile, and hexane, nor in oxygen-free water. In water solution, photolytic degradation occurs and results in the formation of desaminometamitron and a ring-opening polar benzoylacetyl hydrazine (tentatively assigned).
