Description

3-Phenylpropionic Acid (CAS NO 501-52-0) is a versatile aromatic carboxylic acid that serves as a key building block in organic synthesis. Its value lies in its ability to introduce the 3-phenylpropionyl moiety, a structural motif found in various high-value compounds. This intermediate is essential for manufacturers in the pharmaceutical, fragrance, and agrochemical industries seeking reliable and high-purity raw materials.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), antihypertensive agents, and other active pharmaceutical ingredients (APIs).
• Fragrance and Flavor Synthesis: Used in the production of esters and other derivatives that contribute to fruity, floral, and balsamic notes in perfumes and food flavorings.
• Agrochemical Production: Serves as a starting material for synthesizing certain herbicides, fungicides, and plant growth regulators.
• Liquid Crystal & Polymer Chemistry: Acts as an intermediate in the manufacture of monomers and additives for advanced materials.
• Organic Synthesis & Research: Employed in academic and industrial R&D for carbon chain elongation, hydrogenation studies, and as a model compound in methodological development.
