4-Chloro-3-nitrocoumarin

Description:
4-Chloro-3-nitrocoumarin is an organic compound belonging to the coumarin family, characterized by its fused benzene and α-pyrone rings. It features a chloro group at the 4-position and a nitro group at the 3-position of the coumarin structure, which contributes to its unique chemical properties. This compound typically appears as a yellow to orange crystalline solid and is known for its fluorescent properties, making it useful in various applications, including as a fluorescent probe in biological studies. Its molecular structure allows for potential interactions with biological molecules, which can be exploited in research and development. Additionally, 4-Chloro-3-nitrocoumarin may exhibit moderate solubility in organic solvents, while its reactivity can be influenced by the presence of the electron-withdrawing nitro group and the electron-donating characteristics of the coumarin moiety.
