Quality Control

Every batch of our Trisodium 5-[[2-Amino-5-Methyl-4-[[4-[2-(4-Nitro-2-Sulphonatophenyl)Vinyl]-3-Sulphonatophenyl]Azoxy]Phenyl]Azo]Naphthalene-1-Sulphonate is produced under a strict quality management system. We employ advanced analytical techniques including HPLC and spectrophotometry to ensure consistent purity and performance. Comprehensive Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with each shipment to guarantee compliance with your specifications.

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 sealed in a low-humidity environment to prevent absorption of moisture and caking. Keep away from incompatible materials.
