Quality Control

Our 8-[[3-[[3-[(2Z)-2-[4-formyl-6-methyl-5-oxo-3-(phosphonooxymethyl)pyridin-2-ylidene]hydrazinyl]benzoyl]amino]-4-methyl-benzoyl]amino]naphthalene-1,3,5-trisulfonic acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key specifications such as assay (HPLC), related substances, and residual solvents are provided and available upon request to support your quality assurance protocols.

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 tightly sealed to prevent absorption of atmospheric moisture, which can affect stability and performance. For long-term storage, consider using desiccants.
