Description

(1S,3R)-cis-3-Carbomethoxy Cyclopentane-1-Carboxylic Acid is a high-purity, chiral cyclopentane derivative that serves as a critical building block in advanced organic synthesis. This compound is valued for its defined stereochemistry and bifunctional nature, enabling precise molecular construction. It is primarily sought after by research institutions and manufacturers in the pharmaceutical and fine chemical industries for the development of active pharmaceutical ingredients (APIs) and complex specialty molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of novel therapeutic agents, particularly for central nervous system (CNS) and metabolic disorder targets.
• Asymmetric Synthesis: Utilized as a precursor for catalysts or ligands in stereoselective reactions due to its rigid, defined cis-conformation.
• Fine Chemical Production: Serves as a foundational component for creating complex agrochemicals, flavors, and fragrances requiring specific stereochemistry.
• Academic & R&D: Used in medicinal chemistry research for structure-activity relationship (SAR) studies and the exploration of new chemical entities.
• Peptidomimetics: The cyclopentane scaffold can be incorporated to create conformationally restricted peptide analogs.

Quality Control

Every batch of (1S,3R)-cis-3-Carbomethoxy Cyclopentane-1-Carboxylic Acid is manufactured under strict quality management systems. We employ advanced analytical techniques, including chiral HPLC and NMR, to guarantee stereochemical purity and chemical identity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) with detailed chromatographic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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.
