Description

Cyclopentanol, 2-[(2-Methylphenyl)Amino]-, (1R,2R)-Rel- (9Ci) is a chiral, optically active organic compound featuring a cyclopentanol core substituted with an o-toluidine group. This specific stereoisomer is of significant value as a high-purity pharmaceutical intermediate and a versatile chiral building block for asymmetric synthesis. It is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors for the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: Key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and cardiovascular drugs.
• Asymmetric Synthesis Building Block: Employed in the construction of complex molecules requiring high enantiomeric purity for research and process development.
• Agrochemical Research: Used in the development of novel, stereospecific pesticides and herbicides where the specific spatial orientation of the molecule is critical for bioactivity.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing chiral ligands and organocatalysts used in enantioselective transformations.
• Fine Chemical Synthesis: A valuable intermediate for producing specialty chemicals, flavors, and fragrances that require defined stereochemistry.
