Quality Control

Our 2-[4-[(4-Hydroxybiphenyl-3-Yl)Azo]Phenoxy]Ethyl Hydrogen Sulphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance 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 opening to prevent degradation from atmospheric moisture.
