4-Nitrophthalide

Description:
4-Nitrophthalide, with the CAS number 65399-18-0, is an organic compound that belongs to the class of phthalides, which are characterized by a fused benzene and lactone structure. This compound features a nitro group (-NO2) positioned at the 4-position of the phthalide ring, which influences its chemical reactivity and properties. 4-Nitrophthalide is typically a solid at room temperature and may exhibit a yellowish color due to the presence of the nitro group. It is known for its applications in organic synthesis, particularly as an intermediate in the production of dyes, pharmaceuticals, and agrochemicals. The presence of the nitro group can enhance the compound's electrophilic character, making it useful in various chemical reactions, including nucleophilic substitutions. Additionally, 4-Nitrophthalide may exhibit specific solubility characteristics, often being soluble in organic solvents while having limited solubility in water. Safety data should be consulted for handling and storage, as nitro compounds can pose health risks.
