Quality Control

Our Theasinensina is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including identity confirmation by spectroscopic methods and purity determination by high-performance liquid chromatography (HPLC). A Certificate of Analysis (COA) detailing batch-specific results is provided to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 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.
