Description

Cinchonidine Tartrate CAS NO 653-55-4 is a high-purity alkaloid salt derived from cinchona bark, valued for its distinct stereochemistry and chiral properties. This compound is essential as a chiral selector, resolving agent, and catalyst in asymmetric synthesis, enabling the production of enantiomerically pure pharmaceuticals and fine chemicals. It is a critical material for research laboratories, pharmaceutical development, and manufacturers of advanced intermediates requiring precise stereochemical control.

Application

• Chiral Resolution Agent: Used in the separation of racemic mixtures of carboxylic acids and other chiral compounds via diastereomeric salt formation.
• Asymmetric Synthesis Catalyst: Employed as a chiral ligand or organocatalyst in stereoselective carbon-carbon bond-forming reactions.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of specific active pharmaceutical ingredients (APIs) and bioactive molecules.
• Analytical Chemistry Standard: Utilized as a reference standard in HPLC and other chromatographic methods for method development and quality control.
• Research & Development: Fundamental tool in academic and industrial R&D for studying chirality, catalysis, and reaction mechanisms.
• Fine Chemical Synthesis: Applied in the production of specialty chemicals, flavors, and fragrances where enantiopurity is required.
