Detailed Description
1-Hexen-3-one (CAS 1629-60-3), also known as vinyl propyl ketone, is an unsaturated aliphatic ketone with the molecular formula C₆H₁₀O and molecular weight 98.14 g/mol. It appears as a colorless to pale yellow liquid with a pungent, characteristic odor. The unique combination of a carbon-carbon double bond and a carbonyl group in its structure gives it high reactivity, making it a valuable building block in the synthesis of aroma chemicals, flavors, fragrances, and pharmaceutical intermediates. It is used extensively in the flavor and fragrance industry to impart green, fruity, and vegetable-like notes (e.g., tomato, mushroom, and tropical fruits).
