Quality Control

Our 4,4'-Dimethoxy-α,β-dimethylstilbene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
