Quality Control

Our 2-(3-tert-Butyl-5-Oxo-2-Pyrazolin-1-Yl)-1,4-Benzenedisulfonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
