Quality Control

Our Chromate,Bis[4-[[3-[(5-Chloro-2-Hydroxyphenyl)Azo]-2,4-Dihydroxyphenyl]Azo]-3-Hydroxy-7-Nitro-1-Naphthalenesulfonato]-,Disodium Hydrogen is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as assay, heavy metal content, and spectroscopic identity are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance and stability.
