Bispyribac Chemical Properties,Usage,Production

Uses

2,6-Bis((4,6-dimethoxypyrimidin-2-yl)oxy)benzoic acid is a useful research chemical.

Definition

ChEBI: Bispyribac is a member of the class of benzoic acids that is benzoic acid substituted by (4,6-dimethoxypyrimidin-2-yl)oxy groups at positions 2 and 6. Its sodium salt is used as a broad spectrum post emergent herbicide for the control of grasses, sedges and broadleaf weeds in rice crops. It has a role as a herbicide. It is an aromatic ether, a member of pyrimidines, a member of benzoic acids and a monocarboxylic acid. It is a conjugate acid of a bispyribac(1-).

Synthesis

303-07-1

113583-35-0

125401-75-4

The general procedure for the synthesis of 2,6-bis((4,6-dimethoxypyrimidin-2-yl)oxy)benzoic acid from 2,6-dihydroxybenzoic acid and 2-methanesulfonyl-4,6-dimethoxypyrimidine was as follows: 0.04 mol of 2,6-dihydroxybenzoic acid, 0.05 mol of 2-methanesulfonyl-4,6-dimethoxypyrimidine, 0.004 mol of tetra butylammonium bromide and 0.08 mol of potassium carbonate in a reaction vessel. 300 mL of toluene was added as a solvent and heated to reflux for 8 to 10 hours. Upon completion of the reaction, the reaction mixture was cooled to room temperature and the solid product was separated by filtration. The filter cake was washed with toluene and subsequently dried. The dried solid product was mixed with 500 mL of water and 30% hydrochloric acid was added slowly and dropwise with stirring to adjust the pH of the system to 3 to 4. It was filtered again and dried to give 15.7 g of the gray solid product 2,6-bis((4,6-dimethoxypyrimidin-2-yl)oxy)benzoic acid with a purity of 97% and a yield of 85%.
