Quality Control

Every batch of our Trisodium n-[5-Hydroxy-6-[[5-[[2-(Sulphonatooxy)Ethyl]Sulphonyl]-2-Methoxyphenyl]Azo]-7-Sulphonato-2-Naphthyl]Succinamate is produced under a strict quality management system. We ensure consistent purity and performance through rigorous in-process and final testing, including advanced chromatographic analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
