Description

(1S,2S)-(+)-n-(4-Toluenesulfonyl)-1,2-Diphenylethylenediamine is a high-purity chiral diamine derivative, serving as a critical building block and ligand in asymmetric synthesis. Its value lies in its ability to induce high enantioselectivity in catalytic reactions, which is essential for producing single-isomer pharmaceutical intermediates and fine chemicals. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing new active ingredients and advanced materials.

Application

• As a chiral ligand or catalyst in asymmetric hydrogenation and carbon-carbon bond-forming reactions.
• As a key synthetic intermediate in the production of enantiomerically pure pharmaceutical active ingredients (APIs).
• In the research and development of novel agrochemicals requiring specific stereochemistry.
• As a resolving agent for the separation of racemic mixtures of acids or other compounds.
• In academic and industrial research for methodological studies in organic and organometallic chemistry.
• For the synthesis of complex natural products and fine chemicals where stereocontrol is paramount.
