Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques, including HPLC and IR spectroscopy, to verify identity, purity, and consistency. Certificates of Analysis (COA) are available upon request, detailing batch-specific results for all critical parameters.

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). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be opaque or stored in darkness.
