Quality Control

Our 6-Mercapto-2H-1,4-benzoxazin-3(4H)-one is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, prolonged exposure to air should be minimized. Recommended storage temperature is 2-8°C for long-term stability.
