2-Phenylpropionic acid, also known as α-ethylphenylacetic acid, finds its commercial and industrial applications primarily in the fragrance and flavor industry. This compound is used as a key intermediate in the synthesis of various aromatic compounds that contribute to the formulation of perfumes, air fresheners, and other scented products. Its sweet, floral scent makes it a popular choice for enhancing the olfactory profile of numerous consumer goods.
In addition to its role in fragrances and flavors, 2-Phenylpropionic acid has significant applications in the pharmaceutical industry. This compound is a precursor in the synthesis of certain non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and ketoprofen. Its chemical structure serves as a building block for the production of these medications, which are widely used for pain relief and inflammation management. The versatility of 2-Phenylpropionic acid makes it a valuable starting material for the pharmaceutical synthesis of various therapeutic agents.
The medicinal applications of 2-Phenylpropionic acid extend beyond NSAIDs to include its use as a chiral auxiliary in asymmetric synthesis. This compound can serve as a chiral source of the 1-phenylethyl fragment, allowing for the creation of enantiomerically pure molecules with specific biological activities. By harnessing the chirality of 2-Phenylpropionic acid, researchers can manipulate the stereochemistry of drug molecules to enhance their efficacy and reduce unwanted side effects. This unique property makes 2-Phenylpropionic acid a valuable tool in the development of novel pharmaceutical compounds.
⚗️ Chemical & Physical Properties
2-Phenylpropionic acid, also known as alpha-phenylpropionic acid, appears as a white crystalline solid with a faint odor. It is commonly used in the synthesis of various pharmaceuticals and fragrances due to its aromatic properties.
With a molar mass of approximately 150.17 g/mol and a density of 1.08 g/cm³, 2-Phenylpropionic acid is more similar in molar mass and density to common food items such as sugar and salt than to heavier oils and fats.
The melting point of 2-Phenylpropionic acid is around 55°C, while its boiling point is approximately 232°C. These values are significantly higher than those of many common food items, such as water and vegetable oils, which have lower melting and boiling points.
2-Phenylpropionic acid is sparingly soluble in water and exhibits low viscosity. This contrasts with many common food items like sugar and salt, which are highly soluble in water and have higher viscosities when dissolved.
🏭 Production & Procurement
2-Phenylpropionic acid, also known as alpha-ethylhydrocinnamic acid, is typically produced through a Friedel-Crafts acylation reaction. This reaction involves the acylation of benzene with propionic anhydride in the presence of a Lewis acid catalyst, such as aluminum chloride. The resulting product is then hydrolyzed to yield 2-Phenylpropionic acid.
In terms of procurement, 2-Phenylpropionic acid can be purchased from chemical suppliers specializing in organic acids. It is often available in both liquid and solid forms, depending on the requirements of the buyer. The acid can be transported in bulk containers, such as drums or tanks, or in smaller quantities in sealed containers to prevent leakage or contamination during transit.
