Quality Control

Our 1,2-Cyclopentanedicarbonyldichloride,(1R,2R)-Rel-(9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure compliance with exacting research and pharmaceutical-grade standards. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided to guarantee batch-to-batch consistency and traceability for your critical applications.

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.
