Lyral, chemically identified as 4-(4-Hydroxy-4-methylpentyl)cyclohex-3-ene-1-carbaldehyde, is a testament to the intricate science behind perfumery. This synthetic aroma chemical has been a cornerstone ingredient, celebrated for its unique and desirable olfactory profile. Understanding its lyral chemical structure applications offers a glimpse into the molecular artistry that creates captivating scents.

The synthesis of Lyral typically involves a multi-step process, often starting from readily available precursors. One common pathway involves a Diels-Alder reaction between myrcene and acrolein, yielding a cyclohexenecarbaldehyde intermediate. Subsequent acid-catalyzed hydration of this intermediate leads to the formation of the tertiary alcohol, completing the synthesis of Lyral. The precision in controlling these chemical reactions is crucial for achieving the desired purity and scent characteristics, highlighting the importance of lyral synthesis and packaging in maintaining quality.

Lyral's physical properties are as important as its aroma. It is typically described as a colorless to pale yellow liquid. Its assay, often around 98%, indicates a high level of purity. Key physical parameters such as refractive index and density are carefully monitored to ensure consistency. These details are vital for formulators who rely on precise specifications when incorporating Lyral into their compositions, making the lyral fragrance properties a subject of detailed study.

The olfactory profile of Lyral is perhaps its most defining characteristic. It possesses a soft, delicate floral scent reminiscent of lily of the valley, cyclamen, and lilac. This makes it an excellent choice for creating authentic floral accords and for enhancing existing floral notes. Its ability to blend seamlessly with other fragrance ingredients and its considerable tenacity mean that Lyral contributes significantly to the overall diffusion and longevity of a perfume, a factor crucial in understanding fine fragrance components.

While Lyral has faced regulatory scrutiny due to its potential for skin sensitization, its chemical ingenuity and olfactory contribution remain significant. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing access to a wide range of aroma chemicals, supported by comprehensive technical data. Understanding the science behind ingredients like Lyral allows perfumers to make informed decisions, navigate regulatory challenges, and continue to innovate within the field of perfumery. Exploring the nuances of the lyral CAS number uses remains valuable for historical context and specific applications.
