1-Ethenyl-1H-pyrrole-2,5-dione

Description:

1-Ethenyl-1H-pyrrole-2,5-dione, also known as 2,5-dioxopyrrole, is an organic compound characterized by its pyrrole ring structure with a vinyl group attached at the 1-position and two carbonyl groups at the 2 and 5 positions. This compound typically appears as a yellow to orange solid and is known for its reactivity due to the presence of the electron-deficient pyrrole ring, which can participate in various chemical reactions, including electrophilic substitutions and polymerization. It is soluble in organic solvents, such as dichloromethane and acetone, but has limited solubility in water. The compound is of interest in materials science and organic synthesis, particularly in the development of dyes and pigments due to its conjugated system, which can absorb light effectively. Additionally, its derivatives may exhibit biological activity, making it a subject of research in medicinal chemistry. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested.
