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) detailing batch-specific results 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 (typically 15-25°C). Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition.
