Quality Control

Our 3,7-Diaminodibenzothiophene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your quality assurance and regulatory needs.

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, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
