Quality Control

Our 2,3-Dihydro-5-Hydroxy-2,2-Dimethyl-3-(3-Oxobutyl)-7-Pentyl-4H-1-Benzopyran-4-One is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets the high standards required for pharmaceutical research. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment.

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.
