For professionals in the fragrance and flavor industries, understanding the molecular underpinnings of aroma chemicals is key to unlocking their full potential. Cinnamyl Cinnamate (CAS 122-69-0), a valued ester, owes its characteristic sweet, balsamic scent and its efficacy as a fixative to its unique chemical structure. As a supplier of high-quality chemical intermediates, we explore the chemistry that makes Cinnamyl Cinnamate so indispensable.

Molecular Composition and Synthesis

Cinnamyl Cinnamate is an ester formed from the reaction between cinnamic acid and cinnamyl alcohol. Its molecular formula is C₁₈H₁₆O₂, with a molecular weight of approximately 264.32 g/mol. The structure consists of two phenylpropene moieties linked by an ester group. Specifically, it is the ester formed between the carboxyl group of cinnamic acid and the hydroxyl group of cinnamyl alcohol. The presence of conjugated double bonds within the phenylpropene chains contributes to its aromatic character and stability.

Structure-Odor Relationship

The characteristic aroma of Cinnamyl Cinnamate—sweet, balsamic, and subtly floral with spicy nuances—is a direct result of its molecular architecture. The phenyl rings, combined with the ester linkage and the unsaturated aliphatic chains, interact with olfactory receptors in the human nose to elicit these specific scent perceptions. The complexity of the molecule allows for a richer, more nuanced aroma compared to simpler esters, making it highly sought after in fine perfumery.

Fixative Properties Explained

The fixative ability of Cinnamyl Cinnamate is also rooted in its chemical structure. Its relatively high molecular weight and the presence of aromatic rings contribute to its low volatility. This means that the molecule evaporates much slower than many top and middle notes in a fragrance. When incorporated into a perfume, it acts as a 'bridge' between the volatile top notes and the heavy base notes, helping to bind them together and ensure a more gradual and prolonged release of the overall scent. This property is crucial for developing fragrances that offer a complex, evolving journey on the skin.
