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. Our quality management system supports the provision of material for research and development under strict quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its nature of being easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from strong oxidizing agents.
