Quality Control

Our Chromate(3-), Bis3-4,5-Dihydro-3-Methyl-5-(Oxo-.Kappa.O)-1-Phenyl-1H-Pyrazol-4-Ylazo-.Kappa.N1-4-(Hydroxy-.Kappa.O)-5-Nitrobenzenesulfonato(3-)-, Sodium Dihydrogen is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric humidity.
