Benzoic acid, 4-methoxy-, 1,1′-anhydride

Description:

Benzoic acid, 4-methoxy-, 1,1′-anhydride, commonly known as 4-methoxybenzoic anhydride, is an organic compound characterized by its anhydride functional group derived from 4-methoxybenzoic acid. It typically appears as a white to off-white solid and is known for its moderate solubility in organic solvents such as ethanol and acetone, while being less soluble in water. The compound exhibits a melting point that is indicative of its crystalline structure. Its chemical formula reflects the presence of both methoxy and anhydride functionalities, which contribute to its reactivity, particularly in acylation reactions. 4-Methoxybenzoic anhydride is utilized in organic synthesis, particularly in the preparation of esters and other derivatives, and may also serve as an intermediate in the production of pharmaceuticals and agrochemicals. Safety data indicates that it should be handled with care, as it may cause irritation to the skin and eyes. Proper storage in a cool, dry place away from incompatible materials is recommended to maintain its stability.

4-Methoxybenzoic anhydride

CAS: 794-94-5

4-Methoxybenzoic anhydride is a nonsteroidal anti-inflammatory drug (NSAID) that has a hydroxy group, which makes it susceptible to nucleophilic attack. The reaction mechanism of 4-methoxybenzoic anhydride involves hydroxyl group and phosphorus pentachloride. Kinetic data for the reaction was obtained from kinetic studies. The kinetic study found that the rate of the reaction increased with increasing concentration of amines and amides in the reaction mixture. 4-Methoxybenzoic anhydride has been shown to have antiinflammatory activity in various tests on animals, including rats, guinea pigs, and rabbits. The mechanism of this activity may be due to its ability to inhibit prostaglandin synthesis by blocking cyclooxygenase enzyme activity.
