Quality Control

Our Nigeran is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and monosaccharide analysis to confirm identity, purity, and structural integrity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place, ideally at 2-8°C for long-term stability. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
