Quality Control

Our 2-[[6-Acetamido-1-Hydroxy-3-Sulpho-2-Naphthyl]Azo]-6-[[2-(Sulphooxy)Ethyl]Sulphonyl]Naphthalene-1-Sulphonic Acid is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided to guarantee compliance with 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). Keep away from strong oxidizing agents. Due to the presence of sulphonic acid groups, the material is hygroscopic; protect from excessive moisture to prevent caking or degradation.
