Quality Control

Our (1Aalpha,4Aalpha,7Alpha,7Abeta,7Balpha)-(-)-1A,2,4A,5,6,7,7A,7B-Octahydro-1,1,4,7-Tetramethyl-1H-Cycloprop[E]Azulene is produced and tested under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity and identity confirmation, to ensure it meets the high standards required for synthesis and research. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity, specific rotation, and other critical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
