Quality Control

Our N,1-Dimethyl-1H-Pyrazol-4-Amine Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and KF titration for moisture content, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, ensuring full traceability and compliance with your internal quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product should be stored in a cool, dry place, ideally under an inert atmosphere such as nitrogen or argon after opening. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
