Quality Control

Our pentasodium 3-[[4-[[4-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]-5-sulphonato-1-naphthyl]azo]-6-sulphonato-1-naphthyl]azo]naphthalene-1,5-disulphonate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthesis processes. Each lot is analyzed to confirm identity, strength, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific tests is provided with every shipment to support your quality assurance and regulatory needs.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect purity and performance.
