Quality Control

Every batch of 3,5-Dimethyl-1-Propyl-1H-Pyrazol-4-Amine Hydrochloride is manufactured under a cGMP-compliant quality management system and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our standard pharmaceutical intermediate grade meets stringent internal specifications, with comprehensive Certificates of Analysis (COA) provided for each lot. We support our clients' regulatory needs with full traceability and documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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. Keep away from incompatible materials.
