Quality Control

Our 3,3'-[[4-[(2-Chloro-4,6-Dinitrophenyl)Azo]Naphthyl]Imino]Bispropane-1,2-Diol is produced under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques like HPLC and NMR to verify identity and assay. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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. Keep away from incompatible materials.
