Quality Control

Our Mnp-Gal is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for sensitive research applications. Each lot undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a desiccated environment to prevent degradation. For long-term stability, consider storage at 2-8°C.
