Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and diagnostic use. Each batch is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to verify identity, purity, and functional integrity. Certificates of Analysis (COA) detailing lot-specific results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under desiccant. This compound is strictly light-sensitive (protect from all light exposure) and may be incompatible with strong oxidizers. Allow the vial to warm to room temperature before opening to minimize moisture condensation. For long-term stability, store under inert atmosphere.
