Quality Control

Every batch of Nobotanin I is produced and analyzed under strict quality management protocols to ensure identity, purity, and consistency. Our standard grade meets specifications suitable for research and development use, with comprehensive testing including HPLC for assay and related substances. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with the agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
