Trifloxysulfuron is a post-emergence herbicide. It has a low aqueous solubility and, based on its chemical properties, is mobile and may leach to groundwater in some situations. It may be persistent in soil systems under certain conditions. It has a low mammalian toxicity and is a skin and eye irritant. It has a low level of toxicity to fish and aquatic invertebrates but is more toxic to honeybees and earthworms.

Trifloxysulfuronis is a herbicidal compound, which can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process.

Trifloxysulfuron is commercially produced via a sulfonylurea synthesis starting from 2-amino-4,6-dimethoxypyrimidine, which is sulfonylated with 2-(trifluoromethoxy)benzenesulfonyl chloride under basic conditions. The resulting sulfonamide is activated with triphosgene to form the sulfonyl isocyanate, which undergoes condensation with methyl 2-amino-4-(trifluoromethyl)pyrimidine-5-carboxylate to build the urea bridge. Final hydrolysis, methyl esterification, and recrystallisation yield trifloxysulfuron (sodium salt).

Aborbed by shoots and roots and translocated. Inhibits plant amino acid synthesis - acetohydroxyacid synthase AHAS
