Quality Control

Our production of 4-[4-[2-(3-Ethyl-2(3H)-Benzothiazolylidene)-1-Methylethylidene]-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-1-Yl]Benzenesulphonic Acid adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical quality attributes are provided with each shipment to guarantee traceability and compliance.

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 to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
