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 and purity. 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, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere for long-term stability. Keep away from heat, sparks, and open flame.
