Quality Control

Our 2',5'-Dimethoxy-[1,1':4',1''-Terphenyl]-4,4''-Diamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high chemical purity and identity. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment. We support custom synthesis and can tailor specifications to meet specific research or production grade requirements.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
