overview | o-nitrophenylacetic acid is a widely used organic synthesis intermediate. O-nitrophenylacetic acid can be used to synthesize benzofuran-2 (3H)-ketone by ammonium sulfide reduction, diazotization and hydrolysis. Benzofuran-2 (3H)-ketone is an important organic synthesis intermediate, which can be used to synthesize medicine, pesticides and new antioxidants. |
application | o-nitrophenylacetic acid is an excellent herbicide, around which a series of drugs and fine chemical products can be developed, such as non-steroidal new drug biphenylacetic acid and high-efficiency antihypertensive drug aminoacylneamine, etc. O-nitrophenylacetic acid can also form luminescent materials with good properties with rare earth metals, so it is widely used in rare earth functional materials. |
