Quality Control

Our Thiarubrine D is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, MS) for structural confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes. We support research and development with materials suitable for use as analytical reference standards.

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). For long-term storage, consider storing under inert atmosphere at -20°C to maximize stability. Keep the container tightly sealed in a dry environment to prevent any potential degradation.
