Applications
2(5H)-Furanone is employed in the preparation of 5-substituted 2(5H) furanones (gamma-butenolides) catalyzed by bifunctional aminothiourea and aminosquaramide organocatalysts through direct aldol reaction with aromatic aldehydes. Further, it is used in the synthesis of lignans by Michael addition reactions. In addition to this, it is used in three-component Michael-Aldol reactions with an aldehyde and thiolate or carbanion.

Solubility
Immiscible with water.

Notes
Light and moisture sensitive. Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.
