Quality Control

Our 3-(3-Thienyl)-1H-Pyrazole is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing including HPLC for purity, NMR for structural confirmation, and KF titration for water content to ensure it meets the specified Saltdata (0.7H2O). A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production standards.

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 nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
