Quality Control

Our 1H-Pyrazole-3-carboxylic acid, 4-[[5-[(5-chloro-2-fluoro- 6-methyl-4-pyrimidinyl)amino]-2-sulfophenyl]azo] -1-(2,5-disulfophenyl)-4,5-dihydro-5-oxo-, tetrasodium salt is produced under a strict quality management system to ensure batch-to-batch consistency and purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) documenting identity, purity, and related substances 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 after opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
