Description

Cyclopentanecarboxamide, 1-Amino-2-Ethyl-, (1R,2S)- (9Ci) is a chiral, non-natural amino acid derivative featuring a cyclopentane ring system. This compound serves as a high-value chiral building block and intermediate in advanced organic synthesis, prized for its defined stereochemistry. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and synthesis of novel drug candidates, particularly in central nervous system (CNS) and metabolic disorder therapeutics.
• Agrochemical Synthesis: Used in the development of advanced, stereoselective pesticides and herbicides where specific chirality impacts biological activity.
• Asymmetric Catalysis: Employed as a ligand precursor or a chiral auxiliary in catalytic processes to induce stereoselectivity.
• Peptidomimetics Research: Serves as a constrained, non-proteinogenic amino acid analog in the design of peptide-like molecules with enhanced stability and bioavailability.
• Chemical Biology Probes: Utilized in the synthesis of specialized probes for studying enzyme mechanisms and protein-ligand interactions.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis projects requiring high-purity, stereochemically defined intermediates.

Quality Control

Our Cyclopentanecarboxamide, 1-Amino-2-Ethyl-, (1R,2S)- (9Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for pharmaceutical R&D. Certificates of Analysis (COA) detailing identity, purity, and chiral excess are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
