Understanding the fundamental chemistry of the materials we use is crucial for optimizing their application and ensuring predictable outcomes. Ethyl 3-phenylpropionate (CAS 2021-28-5) is a fascinating organic compound whose synthesis and properties make it invaluable across various sectors, from pharmaceuticals to fine fragrances. NINGBO INNO PHARMCHEM CO.,LTD. is pleased to provide a closer look at the chemical characteristics that define this important ester.

Ethyl 3-phenylpropionate, with the molecular formula C11H14O2 and a molecular weight of 178.23 g/mol, is an ester derived from the reaction of 3-phenylpropanoic acid and ethanol. The primary method for its synthesis involves esterification, a classic organic chemistry reaction. This process typically involves reacting 3-phenylpropanoic acid with ethanol in the presence of an acid catalyst, such as sulfuric acid, to drive the reaction forward and yield the desired ester. An alternative synthesis route can involve the hydrogenation of ethyl cinnamate.

Physically, ethyl 3-phenylpropionate presents as a clear, colorless to light yellow liquid. Its density is approximately 1.017 g/cm³, and its refractive index is around 1.494. The boiling point is notable, reported at around 245.9 °C at atmospheric pressure, indicating a relatively low volatility compared to smaller esters. Its flash point is around 103.2 °C, classifying it as a combustible liquid that requires careful handling, especially concerning ignition sources.

A key characteristic of ethyl 3-phenylpropionate is its solubility profile. Due to its ester functional group and hydrocarbon chain, it exhibits good solubility in organic solvents like ethanol and chloroform but has limited solubility in water. This property is typical for esters of this size and structure and influences its applications and how it is processed in various chemical reactions and formulations.

The compound's chemical reactivity is characteristic of esters. It can undergo hydrolysis in the presence of acids or bases to revert back to 3-phenylpropanoic acid and ethanol. It is also susceptible to transesterification and can react with strong oxidizing agents. Understanding these reactions is important for storage and for designing chemical processes where ethyl 3-phenylpropionate is used as a reactant or intermediate.
