Quality Control

Our 1,2,3,5,6-Penta-o-Benzoyl-D-Galactofuranose is produced under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment, NMR for structural confirmation, and specific optical rotation measurement. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications to support your quality assurance and regulatory needs.

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 compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using a desiccant in the storage area.
