Description

S,R,R-Csdpen CAS NO 637357-55-2 is a high-purity, chiral chemical compound of significant interest in advanced synthetic chemistry. Its defined stereochemistry makes it a valuable building block for the research and development of novel active pharmaceutical ingredients (APIs) and fine chemicals. This product is primarily targeted at pharmaceutical R&D laboratories, contract research organizations (CROs), and manufacturers of specialty intermediates seeking reliable, high-quality chiral synthons.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Asymmetric Synthesis: Employed as a sophisticated building block or ligand in catalytic asymmetric reactions to induce chirality.
• Chemical Research: Used in academic and industrial R&D for developing new synthetic methodologies and exploring structure-activity relationships (SAR).
• Fine Chemical Production: Serves as a critical intermediate in the manufacture of high-value specialty chemicals and agrochemicals.
• Reference Standard: Utilized as an analytical standard for quality control and method development in chiral analysis (e.g., HPLC, SFC).

Quality Control

Our S,R,R-Csdpen is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for pharmaceutical and research applications. A Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
