Halosulfuron methyl Chemical Properties,Uses,Production
Uses
Herbicide.
Definition
ChEBI: Halosulfuron-methyl is a member of pyrazoles.
Production Methods
Halosulfuron-methyl is synthesised through a multi-step process that builds its sulfonylurea herbicidal structure. The synthesis typically begins with 3-chloro-1-methylpyrazole-5-hydroxy-4-methyl formate as the starting material, which undergoes condensation with dimethylaminothioformyl chloride to form a thioformyloxy intermediate. This is followed by a rearrangement reaction to yield a dimethylaminothioyl derivative. The next step involves chlorosulfonation, introducing a sulfonyl chloride group at the pyrazole ring. This intermediate is then subjected to ammoniation, converting the sulfonyl chloride into a sulfonamide. Finally, the sulfonamide is coupled with a pyrimidine derivative, such as 4,6-dimethoxypyrimidine-2-amine, through a carbamoylation reaction, and the resulting compound is methylated to produce the active halosulfuron-methyl ester.
Hazard
Moderately toxic by ingestion.
Mechanism of action
Systemic, selective, acts by inhibiting biosynthesis of essential amino acids valine and isoleucine restricting plant growth. Inhibits plant amino acid synthesis - acetohydroxyacid synthase AHAS
