Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. We employ advanced analytical techniques, including HPLC, NMR, and mass spectrometry, to verify identity, purity, and consistency. Certificates of Analysis (COA) are available upon request, detailing batch-specific results. Our quality management system is designed to support research and commercial-scale applications where traceability and reliability are paramount.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect purity and performance. Keep away from incompatible materials such as strong bases and oxidizing agents.
