Quality Control

Our 1-Hydroxy-5-Sodiosulfo-2-Naphthalenediazonium is produced under strict quality management protocols to ensure batch-to-batch consistency and reliability. We employ advanced analytical techniques including HPLC, NMR, and titration to verify identity, purity, and composition. 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 area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong acids, bases, and reducing agents.
