Quality Control

Our 2-(Phenyldiazenyl)Terephthalic Acid is manufactured under a strict quality management system. Every 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 each shipment, confirming compliance with agreed specifications.

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 in a dry environment to prevent degradation. Keep away from incompatible materials.
