Quality Control

Our 5-4-(7-Amino-1-Hydroxy-3-Sulfonaphthalen-2-Ylazo)Naphthalen-1-Ylazoisophthalicacidtrisodiumsalt is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use in sensitive applications. Certificates of Analysis (COA) documenting purity, heavy metal content, and other critical parameters are provided with every shipment to guarantee traceability and compliance.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product stability and performance.
