Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to verify identity, purity, and consistency for every batch. Certificates of Analysis (COA) detailing all specifications are available upon request. Our quality management system is designed to support cGMP and ISO guidelines for research and commercial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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. For long-term storage, consider using desiccants.
