Quality Control

Our Maltononaose is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including HPLC, HPAEC-PAD, and NMR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under anhydrous conditions. For long-term stability, consider storage under inert atmosphere or in a desiccator.
