Quality Control

Our production of (-)-7-[(1,4,4A,5,6,7,8,8A-Octahydro-6,7-Dihydroxy-2,5,5,8A-Tetramethylnaphthalen-1-Yl)Methoxy]-2H-1-Benzopyran-2-One adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including chiral purity analysis, to ensure identity, potency, and purity meet exacting customer specifications. Certificates of Analysis (COA) detailing all test results are provided as standard, ensuring full traceability and compliance with cGMP principles where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and potential degradation. Recommended storage temperature is 2-8°C for optimal stability.
