Description

(S)-(+)-Nirvanol CAS NO 65567-34-2 is a high-purity chiral compound belonging to the hydantoin class, specifically the (S)-enantiomer of Nirvanol. This compound is of significant value as a key chiral intermediate and building block in advanced organic synthesis, particularly for the development of pharmaceuticals and bioactive molecules. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require enantiomerically pure materials for asymmetric synthesis and active pharmaceutical ingredient (API) development.

Application

• Pharmaceutical Intermediate: A critical chiral building block in the synthesis of enantiomerically pure drugs, particularly those targeting the central nervous system.
• Asymmetric Synthesis: Used as a starting material or resolving agent in catalytic and stoichiometric asymmetric reactions to induce chirality.
• Agrochemical Research: Serves as a precursor in the development of chiral pesticides and herbicides where specific stereochemistry affects biological activity.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances that require high stereochemical purity.
• Academic & R&D: A valuable reference standard and reagent for methodological development in synthetic organic and medicinal chemistry laboratories.
• Biochemical Studies: Can be used in studies investigating enzyme-substrate interactions or as a ligand in chiral separation sciences.
