Quality Control

Every batch of our n-Desmethyl U-47700 (Crm) is manufactured and handled under strict quality management systems. The material undergoes comprehensive analytical testing, including chromatographic purity assessment and structural confirmation, to ensure it meets the exacting standards required for a certified reference material. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and traceability to in-house reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccant use.
