3-Buten-2-one

Description:
3-Buten-2-one, also known as mesityl oxide, is an organic compound with the molecular formula C4H6O. It is classified as an α,β-unsaturated ketone, characterized by a double bond between the second and third carbon atoms and a carbonyl group at the second position. This compound is a colorless to pale yellow liquid with a distinctive odor, often described as sweet or fruity. It has a relatively low boiling point and is soluble in organic solvents such as ethanol and ether, but has limited solubility in water. 3-Buten-2-one is known for its reactivity, particularly in Michael addition reactions and as a precursor in various organic syntheses. It is used in the production of pharmaceuticals, agrochemicals, and as a solvent in industrial applications. Safety considerations include its flammability and potential health effects upon inhalation or skin contact, necessitating appropriate handling and storage measures.
