Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Each lot is characterized using advanced analytical techniques to confirm identity, purity, and absence of critical metallic impurities. Certificates of Analysis (COA) detailing specific results for each parameter are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent degradation. Handle and store in accordance with all applicable safety regulations.
