Quality Control

Our Cyclopropanecarboxylic Acid, 2-[(Acetylamino)Methyl]-, (1R,2S)-Rel- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with stringent industry standards for advanced intermediates. Certificates of Analysis (COA) detailing identity, purity, and chiral excess are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

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