Quality Control

Our production of Disodium 2-(4,5-Dibromo-6-Oxido-3-Oxoxanthen-9-Yl)Benzoate adheres to stringent quality management protocols. Each batch is analyzed to ensure compliance with agreed-upon specifications, which typically include identity confirmation, purity assay, and control of key impurities. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
