Quality Control

Our (3S,12aS)-5α-Ethyl-3,3aα,4,5,6,7,8,9,11,12-decahydro-4β-hydroxy-3-methyl-11α-[(2S,4S)-tetrahydro-4-methyl-5-oxofuran-2-yl]-2H-furo[3,2-i]pyrrolo[3,2,1-jk][1]benzazepin-2-one is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and structural confirmation via spectroscopic methods, to ensure it meets the stringent requirements for research and development use. A detailed Certificate of Analysis (COA) is provided with every shipment.

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 sensitivity, the product should be handled under an inert atmosphere when appropriate and protected from prolonged exposure to air to prevent oxidation. Keep container tightly sealed when not in use to minimize moisture uptake.
