Quality Control

Our Zpck CAS NO 26049-94-5 is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can supply material compliant with various pharmacopeial standards 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 prevent moisture absorption, which can affect product stability and performance.
