Quality Control

Our Cinprazole is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to confirm identity and meet stringent impurity profiles. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 after opening to prevent degradation from atmospheric moisture.
