Quality Control

Our Autumnolide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your research and production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat sources and incompatible materials. For long-term storage, consider inert atmosphere conditions to maintain optimal stability.
