Description

(2R,4R)-Bppm is a high-purity chiral ligand and organocatalyst, specifically the (2R,4R)-enantiomer of 2,4-bis(diphenylphosphino)pentane. This compound matters for its critical role in facilitating highly selective asymmetric synthesis, enabling the production of enantiomerically pure intermediates and active pharmaceutical ingredients (APIs). It is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors who require precise stereochemical control in their catalytic processes.

Application

• As a chiral ligand in asymmetric hydrogenation and other transition metal-catalyzed reactions.
• For the synthesis of enantiomerically pure pharmaceutical intermediates and active ingredients.
• In the development of novel catalysts for agrochemical and specialty chemical production.
• As a key reagent in academic and industrial research focused on stereoselective synthesis.
• For process development and scale-up in GMP-compliant API manufacturing.
• In the preparation of chiral compounds for material science and electronics applications.
