4-nitro-1,8-naphthalic anhydride

Description:

4-Nitro-1,8-naphthalic anhydride is an organic compound characterized by its anhydride functional group and a nitro substituent on the naphthalene ring system. It typically appears as a yellow to orange crystalline solid and is known for its relatively high melting point. The presence of the nitro group contributes to its reactivity, making it a useful intermediate in organic synthesis, particularly in the production of dyes, pharmaceuticals, and agrochemicals. This compound is soluble in organic solvents such as acetone and chloroform but is generally insoluble in water. Its chemical structure allows for electrophilic substitution reactions, and it can undergo hydrolysis to form the corresponding naphthalic acid. Due to its potential reactivity and the presence of the nitro group, it is important to handle 4-nitro-1,8-naphthalic anhydride with care, as it may pose health risks if inhaled or ingested. Proper safety measures should be taken when working with this compound in laboratory settings.
