3-Bromo-2H-1-benzopyran-2-one, also known as 3-bromo coumarin, is a chemical compound characterized by its fused benzene and pyrone rings, which contribute to its aromatic properties. This compound typically appears as a pale yellow to light brown solid and is known for its moderate solubility in organic solvents like ethanol and dichloromethane, while being less soluble in water. The presence of the bromine atom at the 3-position of the coumarin structure enhances its reactivity, making it useful in various chemical reactions, including electrophilic substitutions. 3-Bromo-2H-1-benzopyran-2-one exhibits fluorescence properties, which can be exploited in biological and analytical applications. It is often utilized in the synthesis of other organic compounds and has potential applications in pharmaceuticals, particularly in the development of anti-inflammatory and anticancer agents. As with many brominated compounds, it is important to handle it with care due to potential toxicity and environmental concerns.
