phenyl propyl phenyl acetate

Phenyl propyl phenyl acetate is an aromatic ester compound with the molecular formula C₁₇H₁₈O₂. It appears as a colorless liquid with characteristic floral and balsamic odor notes reminiscent of hyacinth, rose, and green spicy elements. This compound is also known by several synonyms including 3-Phenylpropyl benzeneacetate and acetic acid, phenyl-, 3-phenylpropyl ester. Classified as a fragrance agent, it is derived synthetically through esterification processes linking benzeneacetic acid derivatives with 3-phenylpropyl alcohol. Its chemical structure and identity are detailed under PubChem CID 67148. Due to its distinctive scent, it is utilized primarily in perfumery and fragrance formulations.

Phenyl propyl phenyl acetate naturally does not occur in significant biological sources but is exclusively synthesized for use as a fragrance ingredient. Its floral and balsam scent profile makes it suitable for incorporation into perfumes, colognes, and various scented products seeking notes of hyacinth, mimosa, narcissus, and rose. It has documented use as a fragrance agent under compliance with IFRA (Global) standards, which recommend maximum usage levels up to 5% in fragrance concentrate formulations. It is not approved for flavoring purposes. This compound is valued for imparting complex floral and spicy overlays to fragrance blends.

Phenyl propyl phenyl acetate exhibits physicochemical properties congruent with many aromatic esters. It has a molecular weight of approximately 254.33 g/mol and presents a specific gravity of 1.077 at 25 °C, indicating it is denser than water. Its vapor pressure is very low at 4.0E-6 mmHg at 25 °C, reflecting low volatility under ambient conditions. The flash point is around 303 °F (150 °C), denoting moderate thermal stability and lower flammability risk compared to lighter esters. The estimated log P of 4.481 suggests significant lipophilicity favoring solubility in organic solvents but limited water solubility. It dissolves readily in alcohols and scarcely in water, influencing formulation behavior in aqueous media. These characteristics inform its handling and application in fragrance manufacturing.
