C13H9NO2

C13H9NO2 is the molecular formula for several chemical compounds, meaning that these compounds contain thirteen carbon atoms, nine hydrogen atoms, one nitrogen atom, and two oxygen atoms. One prominent compound with this formula is isatin. Isatin is an organic compound that can be synthesized and also occurs naturally in certain plants, such as those belonging to the *Isatis* genus. It is characterized by its indole structure with two carbonyl groups. Isatin serves as a precursor in the synthesis of various dyes, including indigo, a well-known blue dye. It also finds applications in the development of pharmaceuticals due to its diverse biological activities, such as antimicrobial and anticancer properties. The reactivity of isatin stems from its diketone functionality and its indole ring system, allowing for a wide range of chemical transformations. Other isomers with the C13H9NO2 formula also exist, each possessing a unique arrangement of atoms that leads to different physical and chemical properties, and potentially different applications. Research into these isomers continues to explore their potential uses in various scientific and industrial fields.
