Quality Control

Our 4-o-Methyl-2,3-o-Benzal-D-Mannosan is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, NMR for structural confirmation, and loss on drying. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or cGMP-grade requirements.

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 tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
