Quality Control

Our production of 2,2,19,19-Tetramethoxy-8,13-Dimethyl-4,6,8,10,12,14,16-Eicosaheptaene-3,18-Dione adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (NMR, IR, MS), to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, handling and transfer should be minimized under direct light exposure.
