Quality Control

Our 5-(Dimethylamino)-2-((4-(Dimethylamino)Phenyl)(Hydroxy)Methyl)Benzenesulfonic Acid is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is 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 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 strong acids and incompatible materials.
