 |  | β-Lonone Usage And Synthesis |  
 | Chemical Properties | Clear Colorless to Pale Yellow Oil |  | Uses | An aroma compound commonly found in essential oils such as rose oil. β-Lonone is an important fragrance chemical used in perfumery. β-Ionone is effective in the chemoprevention of rat mammary carcinogenesis.
 |  | Uses | It is an important fragrance chemical used in perfumery. The combination of α-ionone and β-ionone is characteristic of the scent of violets and used with other components in flavoring to recreate their scent. |  | Definition | ChEBI: An ionone that is but-3-en-2-one substituted by a 2,6,6-trimethylcyclohex-1-en-1-yl group at position 4. |  | Synthesis Reference(s) | Synthetic Communications, 17, p. 85, 1987 DOI: 10.1080/00397918708063906 Tetrahedron Letters, 30, p. 645, 1989 DOI: 10.1016/S0040-4039(01)80271-9 |  | Flammability and Explosibility | Nonflammable |  | Purification Methods | Convert β-ionone to the semicarbazone (m 149o) by adding 50g of semicarbazide hydrochloride and 44g of potassium acetate in 150mL of water to a solution of 85g of β-ionone in EtOH. |
