Description
Solid
Solid
Azimsulfuron is an N-sulfonylurea that is urea in which a nitrogen attached to one of the nitrogens has been replaced by a 4,6-dipyrimidin-2-yl group while a hydrogen attached to the other urea nitrogen has been replaced by a [1-methyl-4-(2-methyl-2H-tetrazol-5-yl)-1H-pyrazol-5-yl]sulfonyl group. An acetolactate synthase inhibitor, it is used as a herbicide for the control of a variety of broad-leaved and sedge weeds in paddy fields and other aquatic situations. It has a role as a herbicide and an EC 2.2.1.6 (acetolactate synthase) inhibitor. It is an aromatic ether, a biaryl, a N-sulfonylurea, a member of tetrazoles and a pyrazole pesticide.

Azimsulfuron Use and Manufacturing
Using malononitrile as the starting material, it reacts with trimethyl orthoformate and condenses with methylhydrazine to obtain pyrazolamide, which is then reacted with sodium azide to undergo methylation, diazotization, sulfonylation, and amination. Finally, it is condensed with pyrimidine carbamic acid phenyl ester, and the desired product can be obtained by post-treatment.
