Quality Control

Our production of Barium 4-[(4-Ethoxy-2-Sulphonatophenyl)Azo]-3-Hydroxy-2-Naphthoate adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Every lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. Certificates of Analysis (COA) documenting purity, strength, and identity 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 opening to prevent absorption of atmospheric moisture, which can affect product performance.
