Quality Control

Every batch of (4As,12As)-8-Methoxy-3,4,4A,5,6,11,12,12A-Octahydrochrysen-1(2H)-One is produced and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing purity, identity, and impurity profiles as confirmed by advanced analytical techniques including HPLC, GC-MS, and NMR.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which may affect stability and purity. Keep away from incompatible materials.
