Description

(S)-(-)-2-Phenoxypropionic Acid CAS NO 1912-23-8 is a high-purity chiral carboxylic acid, serving as a critical chiral building block and resolving agent in advanced organic synthesis. Its value lies in its ability to impart stereochemical control, enabling the production of enantiomerically pure compounds essential for modern pharmaceuticals and agrochemicals. This product is primarily needed by R&D laboratories and production facilities in the pharmaceutical, agrochemical, and specialty chemical industries for developing active pharmaceutical ingredients (APIs), chiral intermediates, and high-value fine chemicals.

Application

• Chiral Intermediate for Pharmaceutical Synthesis: A key building block in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly non-steroidal anti-inflammatory drugs (NSAIDs) and other therapeutics.
• Resolution Agent: Used as a chiral resolving agent to separate racemic mixtures of amines, alcohols, and other compounds into their pure enantiomers.
• Agrochemical Intermediate: Employed in the synthesis of chiral herbicides, fungicides, and plant growth regulators where specific stereochemistry is required for biological activity.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing chiral ligands used in asymmetric catalysis, such as in hydrogenation or cross-coupling reactions.
• Fine Chemical and Flavor/Fragrance Synthesis: Utilized in the production of high-value specialty chemicals and chiral components for flavors and fragrances.
• Academic and Industrial R&D: A valuable reagent for method development and research in synthetic organic chemistry focused on stereoselective transformations.
