Quality Control

Our production of (4S)-4,4Aβ,5,6,7,7Aβ,8,9-Octahydro-4β,8β-Dihydroxy-6,6,8-Trimethylazuleno[5,6-C]Furan-3(1H)-One adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and chiral analysis to confirm stereochemical integrity, ensuring it meets exacting research-grade specifications. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
