Quality Control

Our 8-Chlorotetrazolo[1,5-a]pyrazine 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 scale-up applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistency.

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 opening to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials.
