Quality Control

Our 3-Acetyl-7,8-Dimethoxy-2-Methyl-1H-Naphtho[2,1-B]Pyran-1-One is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific client requirements for research or cGMP applications.

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 each use to prevent degradation from atmospheric moisture.
