Properties: Colorless or yellow liquid with a distinctive light or floral aroma. Density: 0.822-0.841 g/cm3 (20°C), Boiling Point: 160-180.5°C (varies significantly between sources, possibly related to pressure or purity), Melting Point: -76°C (no data available), Refractive Index: 1.413-1.418 (20°C). Slightly soluble in water, miscible in most organic solvents (e.g., ethanol, ether).

Uses: It is an important organic synthesis intermediate used in the synthesis of fruity, floral, and herbal fragrances and is a key flavoring agent in cosmetics, detergents, and air fresheners. It is used in the Horner-Wadsworth-Emmons reaction to synthesize cis-α,β-unsaturated amides; as a reducing agent in the epoxidation of cyclooctenes; and as a starting material for the synthesis of 2-ethylhexanoic acid using manganese(II) acetate as a catalyst. It is also used as a raw material or additive in paints, disinfectants, pesticides, and leak detectors.
