Description

(R)-Cyclohexylphenylacetic Acid CAS NO 51019-55-7 is a high-purity chiral carboxylic acid building block of significant importance in asymmetric synthesis. Its value lies in its role as a key intermediate for constructing complex molecules with defined stereochemistry, which is critical for biological activity. This product is essential for research and development chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require enantiomerically pure intermediates.

Application

• As a critical chiral intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and anti-inflammatory drugs.
• Building block for the development of novel agrochemicals, including herbicides and fungicides with enhanced efficacy and selectivity.
• Precursor in the preparation of chiral ligands and catalysts used in asymmetric hydrogenation and other enantioselective transformations.
• Starting material for research into new liquid crystal compounds and other advanced organic materials requiring specific stereochemical configurations.
• Use in custom synthesis and contract manufacturing for clients requiring bespoke, enantiomerically pure compounds.
