Benzyl cinnamate

Benzyl cinnamate is an organic compound that is a constituent of various natural products and is used in the flavor and fragrance industry. It is an ester formed from the condensation of benzyl alcohol and cinnamic acid. With the chemical formula C_16H_14O_2, benzyl cinnamate is known for its sweet, balsamic aroma, making it a popular additive in the formulation of perfumes, cosmetics, and flavoring agents.

Properties

Benzyl cinnamate is a white to pale yellow crystalline solid at room temperature. It has a melting point of approximately 34-37°C and a boiling point of about 370°C. This compound is slightly soluble in water but highly soluble in organic solvents such as ethanol and diethyl ether. Its molecular weight is 238.28 g/mol.

Synthesis

The synthesis of benzyl cinnamate typically involves the esterification of cinnamic acid with benzyl alcohol. This reaction can be catalyzed by acids or bases, or it can proceed under enzyme-catalyzed conditions. The choice of catalyst and reaction conditions can affect the yield and purity of the product.

Applications

Fragrance and Flavoring

Benzyl cinnamate's sweet, balsamic odor has made it a valuable component in the fragrance industry. It is used in the formulation of perfumes and scented products, as well as in flavorings for food and beverages. Its application extends to personal care products, where it contributes to the aroma profile of lotions, creams, and soaps.
