Quality Control

Our production of Sodium 5-[(4-Ethoxyphenyl)Azo]-8-[(2-Methoxyphenyl)Azo]Naphthalene-2-Sulphonate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Every lot is analyzed using advanced techniques like HPLC and spectrophotometry to verify identity, strength, and impurity profiles. Certificates of Analysis (COA) documenting all critical specifications 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
