Quality Control

Our production of 4,13-Dihydroxy-8,9-Bis(2-Hydroxypropyl)-7,10-Dimethoxyperylo[1,12-Def]-1,3-Dioxepin-6,11-Dione adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity, spectroscopic identification (IR, NMR), and loss on drying, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
