Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. Each batch is controlled for identity, purity, and key physical parameters. Certificates of Analysis (COA) detailing assay, impurity profiles, and other relevant specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and decomposition. Keep away from strong alkalis.
