Lyral, also known as hydroxyisohexyl 3-cyclohexene carboxaldehyde, is a colorless, viscous liquid with a sweet odor reminiscent of lily of the valley. It is a mixture of isomers and is used as a fragrance ingredient in the perfumery industry. Lyral is prepared by a Diels-Alder reaction of myrcenol and acrolein in the presence of a Lewis catalyst, such as zinc chloride. It has excellent fixative properties and is known to be a suspected fragrance allergen, which may cause skin irritation in some individuals.

Uses

Used in Perfumery:
Lyral is used as a fragrance ingredient for its light floral scent and excellent fixative properties. It is particularly useful in the formulation of perfumes, colognes, and other scented products.
Used in Soap and Cosmetics:
Lyral is used as a fragrance ingredient in the soap and cosmetics industry due to its ability to enhance and prolong the scent of these products. Its fixative properties make it a valuable addition to the formulation of soaps, lotions, creams, and other personal care products.
Used in Fragrance Allergen Research:
As a suspected fragrance allergen, Lyral is also used in the research and development of products that aim to minimize the risk of skin irritation and allergic reactions in sensitive individuals. This application involves the study of its chemical properties and potential allergenic effects, as well as the development of alternative fragrance ingredients with lower allergenic potential.

Trade name

Lydocal (Hangzhou), Lyral? (IFF)

Contact allergens

Lyral ? is a synthetic blend of two isomers, and one of the most frequently encountered allergen in perfumes. It has to be listed by name in the ingredients of cosmet- ics in the EU, according to the seventh amendment of the cosmetic directive 76/768/EEC.

Check Digit Verification of cas no

The CAS Registry Mumber 31906-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,9,0 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 31906-04:
(7*3)+(6*1)+(5*9)+(4*0)+(3*6)+(2*0)+(1*4)=94
94 % 10 = 4
So 31906-04-4 is a valid CAS Registry Number.

A PRACTICAL SYNTHESIS OF MYRCENOL BY PALLADIUM COMPLEX-CATALYZED ELIMINATION REACTION

Kumobayashi, Hidenori,Mitsuhashi, Shigeru,Akutagawa, Susumu,Ohtsuka, Sei

, p. 157 - 160 (2007/10/02)

A Palladium complex-catalyzed elimination reaction of allyl amines was studied to establish a practical process for production of myrcenol.The catalytic elimination occurred smoothly with the cationic Pd(II) complexes.Among a variety phosphorous ligands, the tetramethylene and the pentamethylene diphosphine ligands proved to be the best ligand with respects to the catalytic activity and selectivity.
