Quality Control

Our W 77 is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including identity confirmation by spectroscopic methods (IR, NMR) and purity assessment by HPLC, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
