Quality Control

Our Bs3 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC for purity assessment and spectroscopic methods for structural confirmation. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under anhydrous conditions. For long-term stability, consider storage under an inert atmosphere.
