Description

(S)-(+)-2-Phenylpropionic Acid CAS NO 7782-24-3 is a high-purity, single-enantiomer chiral carboxylic acid, serving as a critical building block in asymmetric synthesis. Its defined stereochemistry is essential for producing optically active compounds with high biological specificity and efficacy. This material is primarily sought by the pharmaceutical industry for the research and development of active pharmaceutical ingredients (APIs), as well as by fine chemical manufacturers for advanced organic synthesis.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other enantiomerically pure APIs.
• Asymmetric Synthesis: Used as a chiral resolving agent or auxiliary in stereoselective chemical reactions to induce desired chirality in target molecules.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, agrochemicals, and advanced materials where optical purity is paramount.
• Biochemical Research: Utilized in academic and industrial R&D for studying enzyme mechanisms, receptor binding, and metabolic pathways.
• Catalyst Ligand Precursor: Serves as a starting material for synthesizing chiral ligands used in homogeneous catalysis.
