5-Bromo-2,4-Dimethoxypyrimidine is an important organic synthesis intermediate. It appears as white crystals or a white powder, soluble in organic solvents such as methanol, ethanol, toluene, and acetone. It has some solubility in hot water and forms salts in acids. It is widely used in the synthesis of sulfonylurea herbicides, such as nicosulfuron, pyrimisulfuron, bensulfuron-methyl, and pyrimisulfuron, with nicosulfuron being the most widely used herbicide. |
