Description

(R)-(-)-Nirvanol CAS NO 65567-32-0 is a high-purity chiral intermediate of significant importance in the synthesis of enantiomerically pure pharmaceuticals and fine chemicals. Its defined stereochemistry is critical for producing active pharmaceutical ingredients (APIs) with the desired biological activity and safety profile. This compound is essential for research and development laboratories, process chemists, and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require a reliable source of a specific enantiomer for asymmetric synthesis.

Application

• As a key chiral building block in the synthesis of enantiopure pharmaceutical compounds.
• Utilized in asymmetric synthesis and catalysis research for developing new synthetic methodologies.
• Acts as a precursor or intermediate in the production of specialty agrochemicals and fine chemicals.
• Employed in academic and industrial R&D for studying structure-activity relationships (SAR).
• Used in the development and scale-up of novel therapeutic agents, particularly in central nervous system (CNS) and metabolic disorder research.
• Serves as a standard or reference material for analytical method development and quality control in chiral separations.
