Quality Control

Our Biil 284 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including identity confirmation by spectroscopic methods and purity determination by chromatography. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

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 minimize exposure to atmospheric humidity.
