Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. We employ advanced analytical techniques, including HPLC and NMR, to verify identity and purity. Certificates of Analysis (COA) detailing purity, impurity profiles, and physical characteristics 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
