1H-Pyrazole-4-carboxylic acid, 1,3-dimethyl-, 4-[2-chloro-3-[(3,5-dimethyl-1H-pyrazol-1-yl)methyl]-4-(methylsulfonyl)benzoyl]-1,3-dimethyl-1H-pyrazol-5-yl ester

Triazole Sulcotrione is used in the making of herbicidal compositions for the controlling of weeds.

Tripyrasulfone is produced through a proprietary multi-step chemical synthesis that involves constructing the core 4-acylpyrazolone scaffold via regioselective acylation of a substituted 2,5-dimethyl-3-hydroxypyrazole ester with a 2-chloro-3-(3,5-dimethylpyrazol-1-ylmethyl)-4-methylsulfonylbenzoyl chloride derivative, followed by sulfonylation and N-alkylation steps to incorporate the 1,3-dimethylpyrazole carboxylate moiety through controlled Friedel-Crafts-type reactions using Lewis acid catalysts like aluminium trichloride in inert solvents such as dichloromethane.
