Quality Control

Our production of trisodium 4-[[4-[[6-(3-tert-butylphenoxy)- 4-chloro-1,3,5-triazin-2-yl]amino]-2-sulphonatophenyl]azo]-4,5-dihydro-5-oxo-1-(4-sulphonatophenyl)-1H-pyrazole-3-carboxylate adheres to stringent quality protocols to ensure batch-to-batch consistency and purity for industrial applications. All materials undergo comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are provided with every shipment to support your quality assurance processes.

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 sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
