Quality Control

Our Celesticetin is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis, including identification, purity assay, and impurity profiling via advanced chromatographic techniques, to ensure it meets the high standards required for research and pharmaceutical applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

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