Quality Control

Our production of 3-[[[3-(Aminocarbonyl)-4,5-Dihydro-5-Oxo-1-Phenyl-1H-Pyrazol]-4-Yl]Azo]-4-Methoxybenzenesulfonic Acid Sodium Salt adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use in sensitive applications. 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 tightly sealed after opening to prevent moisture absorption and degradation.
