2hydroxy3Hbenzofuran3one

2hydroxy3Hbenzofuran-3-one, also known as coumaranone, is an organic compound with the chemical formula C8H6O2. It is a bicyclic molecule consisting of a benzene ring fused to a furan ring, with a hydroxyl group and a ketone functionality. The "3H" designation indicates the position of the hydrogen atom within the furan ring.

Coumaranone exists as a crystalline solid at room temperature. Its chemical structure makes it a derivative of benzofuran, a class of heterocyclic compounds. The presence of both a hydroxyl group and a ketone group provides sites for various chemical reactions.

This compound has found applications in organic synthesis as a building block or intermediate. It can participate in reactions such as alkylation, acylation, and condensation, leading to the formation of more complex molecules. Its derivatives have been explored for potential biological activities, though research in this area is ongoing and may be specific to particular modifications of the coumaranone structure. Coumaranone itself is primarily recognized for its role in synthetic chemistry.
