Quality Control

Our (E)-1-(4-Isocyanatophenyl)-2-Phenyldiazene (Saltdata: Free) is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support custom synthesis and can tailor purity grades to meet specific research or industrial requirements.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
