4-nitrobenzoic anhydride

Description:

4-Nitrobenzoic anhydride is an organic compound characterized by its anhydride functional group derived from 4-nitrobenzoic acid. It typically appears as a yellow crystalline solid and is known for its relatively high melting point. The presence of the nitro group (-NO2) on the aromatic ring contributes to its reactivity, making it a useful intermediate in organic synthesis, particularly in the preparation of various derivatives and in acylation reactions. This compound is generally soluble in organic solvents such as acetone and dichloromethane but has limited solubility in water. Due to its chemical structure, 4-nitrobenzoic anhydride can participate in electrophilic aromatic substitution reactions and is often employed in the synthesis of pharmaceuticals, dyes, and agrochemicals. Safety precautions should be observed when handling this compound, as it may pose health risks, including irritation to the skin and respiratory system. Proper storage in a cool, dry place away from incompatible materials is recommended to maintain its stability and integrity.

4-Nitrobenzoic anhydride

CAS: 902-47-6

4-Nitrobenzoic anhydride is a chemical compound that is used as a reagent in organic synthesis. It can be prepared by reacting magnesium with 4-nitrobenzoyl chloride in tetrahydrofuran. This reaction produces the salt of the acid, which can then be reacted with ethyl acetate to form the diethyl ester. The product can also be prepared by reacting propionyl chloride and peroxide in tetrahydrofuran or by reaction of 1-naphthaldehyde and chloride in acetic acid. 4-Nitrobenzoic anhydride is a salt that has been used as a corrosion inhibitor for metals and as a reducing agent for epoxides. It has also been used to produce other substances, such as methylamines, amines, and nitro compounds. 4-Nitrobenzoic anhydride reacts with nucleophiles such as water or alkalis to produce perox
