Quality Control

Our Succinamic Acid, n-3,6-Disulfo-7-p-(2,3,5-Trichloro-4-Oxo-1(4H)-Pyridyl)Phenylazo-1-Naphthyl-, Trisodium Salt is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and elemental analysis, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request.

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 sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
