Quality Control

Our trans-4-Aminostilbene is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, which includes data from techniques such as HPLC, GC, NMR, and IR spectroscopy. Our quality commitment ensures the material meets the high standards required for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the original packaging. Keep away from heat, sparks, and open flame.
