Description

Cyclopentanecarboxylic Acid, 2-Amino-3-Methyl-, Methyl Ester, (1Alpha,2Alpha,3Alpha)- CAS NO 769894-82-8 is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. This compound matters because its unique cyclopentane scaffold and functional groups make it a versatile precursor for constructing complex molecular architectures with precise three-dimensional control. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients, including potential drug candidates and specialty chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly those targeting central nervous system (CNS) disorders or metabolic diseases.
• Agrochemical Synthesis: Used in the construction of advanced, stereospecific herbicides, fungicides, or insecticides where the specific spatial orientation of the molecule is critical for biological activity.
• Asymmetric Catalysis Ligand Precursor: Serves as a starting material for the synthesis of novel chiral ligands used in asymmetric hydrogenation and other enantioselective transformations.
• Fine Chemical and Specialty Material Production: Employed in the synthesis of complex fragrances, flavors, and advanced materials that require a defined cyclopentane core structure.
• Academic and Contract Research: A valuable reagent for methodological development in organic chemistry and for exploring new synthetic pathways in academic and industrial R&D settings.

Quality Control

Our Cyclopentanecarboxylic Acid, 2-Amino-3-Methyl-, Methyl Ester, (1Alpha,2Alpha,3Alpha)- is manufactured under strict quality systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
