Quality Control

Our Isotanshinone Iia is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods (IR, NMR). We provide Certificates of Analysis (COA) with detailed specifications to ensure compliance with research and development requirements. For cGMP or other specific regulatory grade needs, please contact our technical sales team.

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 light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
