Tribenuron is an herbicide used in the protection of grains and produce crops.

ChEBI: An N-sulfonylurea that is N-(2-carboxybenzenesulfonyl)urea bearing additional methyl and 4-methoxy-6-methyl-1,3,5-triazin-2-yl substituents at position N3. A foliar acting, post-emergence herbicide used to control broa -leaved weeds in cereals, normally used as the methyl variant.

Tribenuron is usually prepared as the methyl ester and is commercially synthesised through sulfonylurea chemistry involving multiple organic reactions. The process begins with the preparation of a sulfonamide intermediate, which is then reacted with a substituted triazine compound to form the sulfonylurea linkage. This key step yields tribenuron-methyl.
