Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality assurance protocols include advanced analytical techniques to verify identity, purity, and performance characteristics. Certificates of Analysis (COA) documenting key specifications are available upon request to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture.
