Quality Control

Our Fk 888 is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
