Quality Control

Our 4-Aminophenyl-β-L-Fucopyranoside is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and diagnostic applications. Each lot undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and specific tests for residual solvents and moisture. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee compliance with your technical 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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
