Quality Control

Our production of 3-(Benzoyloxy)-4-[(4,5-Dihydro-3-Methyl-5-Oxo-1-Phenyl-1H-Pyrazol-4-Yl)Azo]Naphthalene-1-Sulphonyl Chloride adheres to stringent internal quality protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed using advanced techniques like HPLC and NMR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance processes.

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 under anhydrous conditions to prevent degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
