Quality Control

Our Sd-208 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity determination and identity confirmation via spectroscopic methods. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes. We adhere to cGMP principles where applicable to support our customers' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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. For long-term storage, consider using desiccants.
