2-Phenylethyl Phenylacetate is an ester formed from phenylacetic acid and 2-phenylethyl alcohol. Its molecule carries two phenyl rings separated by an ester group. The compound is well known in the fragrance field for its soft, sweet aroma with honey and rose notes. In the chemistry laboratory, 2-Phenylethyl Phenylacetate serves as a non-heterocyclic building block, as a model compound in studies of aromatic esters, and as a reference standard in the analysis of aroma materials and flavour products. Supplied under the TCI brand, it suits both synthetic and analytical work.
Laboratories choose this compound mainly because of its relatively large molecular size. It is much less volatile than short-chain phenylacetate esters, which makes it useful as a fixative component or "base note" in perfume formulation research, where scent needs to last. Chemically, the ester group can be hydrolysed back into its two aromatic components, phenylacetic acid and 2-phenylethyl alcohol. The alpha hydrogens on the phenylacetyl portion also remain available for further reactions. This gives chemists a predictable, well-defined scaffold to work with. Because it is packed in gram quantities, it is handled by weighing, so doses can be measured precisely.
In Indonesia, 2-Phenylethyl Phenylacetate is relevant to laboratories in the perfume, soap, and cosmetics industries that need aroma materials with honey and floral character. Research and development teams can use it to test fragrance formulations and to study how long a scent lasts in finished products. Quality control laboratories can use it as a comparison standard when checking aroma raw materials. University chemistry departments may also use it in teaching and research on ester synthesis, hydrolysis, and the reactivity of aromatic compounds.
