Quality Control

Our Thionium is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere such as nitrogen or argon in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases and incompatible organic solvents.
