3-Nitrophthalic anhydride

Description:

3-Nitrophthalic anhydride is an organic compound characterized by its anhydride functional group and a nitro substituent on the phthalic structure. It is typically a yellow to brown solid at room temperature and is known for its reactivity, particularly in electrophilic aromatic substitution reactions due to the presence of the nitro group, which is a strong electron-withdrawing group. This compound is soluble in organic solvents such as acetone and chloroform but has limited solubility in water. It is primarily used in the synthesis of various chemical intermediates, including dyes, pharmaceuticals, and agrochemicals. Additionally, 3-nitrophthalic anhydride can undergo hydrolysis to form 3-nitrophthalic acid, which retains some of the properties of the anhydride. Safety precautions should be taken 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 essential to maintain its stability and prevent degradation.

3-Nitrophthalic anhydride is a nucleophilic compound that is activated by the addition of hydrochloric acid and chloride. It reacts with dimethyl formamide to produce nitrobenzene, which can be oxidized to nitrobenzoic acid. 3-Nitrophthalic anhydride has been used as a precursor for pomalidomide, a drug used in the treatment of multiple myeloma and other cancers. In this reaction, n-dimethyl formamide reacts with 3-nitrophthalic anhydride to produce nitromethane, which can then be oxidized to nitrobenzoic acid. Molecular modeling studies have shown that 3-nitrophthalic anhydride binds to DNA through hydrogen bonding interactions and the formation of covalent bonds. The solubility data for 3-nitrophthalic anhydride show that it is soluble in water and organic solvents such as acetone or met
