The captivating scents and flavors that enrich our lives are often the result of intricate molecular engineering. Allyl Cyclohexylpropionate (CAS 2705-87-5) is a prime example of how specific chemical structures translate into desirable olfactory and gustatory profiles. This synthetic ester, widely used in perfumery and flavoring, owes its characteristic sweet pineapple aroma and robust performance to its unique chemical makeup.

At its core, Allyl Cyclohexylpropionate is an ester, formed by the esterification reaction between cyclohexylpropionic acid and allyl alcohol. The structure features a cyclohexyl ring attached to a propionate ester group, with an allyl functional group at the ester linkage. This combination is significant. The cyclohexyl ring provides a degree of molecular bulk and stability, contributing to the compound's tenacity and its subtly woody undertones. The propionate chain influences its fruity character, while the allyl group is believed to enhance its diffusion and contribute to its fresh, vibrant top notes.

Chemically, Allyl Cyclohexylpropionate is a colorless liquid with a relatively high boiling point, contributing to its persistence in formulations. Its molecular weight is approximately 196.29 g/mol, and its LogP value of around 4.28 suggests good lipophilicity, which aids in its compatibility with various solvents and oils used in fragrance and flavor compositions. The molecule's stability is also noteworthy, allowing it to withstand a range of pH levels and temperatures encountered in different product matrices, from fine perfumes to detergents and even certain food items.

The olfactory profile of Allyl Cyclohexylpropionate is often described as sweet, fruity, and reminiscent of pineapple, with additional green, waxy, and slightly woody nuances. This complex character arises directly from its chemical structure. The ester functionality typically imparts fruity notes, while the specific arrangement of carbon atoms and functional groups in the cyclohexylpropionate moiety shapes the precise character of the fruitiness and adds the green and woody dimensions.

For professionals in the field, understanding these chemical properties is crucial for effective formulation. It allows for informed decisions about how to best utilize Allyl Cyclohexylpropionate, whether to amplify fruity notes, add longevity to a scent profile, or enhance the sensory appeal of a flavor. The ability to procure this chemical from reliable manufacturers, such as NINGBO INNO PHARMCHEM CO., LTD., ensures that the precise chemical specifications are met, leading to consistent and predictable results in final products.
