Quality Control

Our 1,2-Dihydro-4-(Isopropylamino)-1,5-Dimethyl-3-Oxo-2-Phenyl-3H-Pyrazolium Hydrogen [R-(R*,R*)]-Tartrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with stringent specifications for pharmaceutical intermediates. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles 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 tightly sealed after opening to prevent degradation from atmospheric moisture.
