Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is controlled against stringent in-house specifications to guarantee identity, purity, and performance consistency. Certificates of Analysis (COA) detailing key parameters are available upon request to support your quality assurance protocols.

Storage

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