Description

(S,S)-(+)-2,3-Diphenylsuccinic Acid is a high-purity chiral dicarboxylic acid derivative, serving as a critical building block in asymmetric synthesis. Its defined stereochemistry provides exceptional value for creating enantiomerically pure compounds, which is essential for achieving desired biological activity and material properties. This product is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel active ingredients and chiral ligands.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly for cardiovascular and central nervous system drugs.
• Asymmetric Catalyst Ligand Synthesis: Used to construct sophisticated chiral ligands for transition metal catalysts employed in enantioselective hydrogenation, oxidation, and C-C bond formation reactions.
• Agrochemical Development: Serves as a building block for creating chiral herbicides, fungicides, and plant growth regulators with improved efficacy and environmental profiles.
• Chiral Resolution Agent: Employed for the separation of racemic mixtures of amines, amino alcohols, and other basic compounds due to its ability to form diastereomeric salts.
• Advanced Material Monomer: A potential monomer for synthesizing chiral polymers with specialized optical or mechanical properties for use in sensors and liquid crystal displays.
• Academic & Process Research: A valuable tool for methodological development in organic chemistry and for scaling up novel synthetic routes in process chemistry.
